You must be stoked after delving into the depths of our world, where we are concerned even with seemingly simple theories of how the human brain works or the quality of our images that we used to enhance our content overall. In its way, it does helps to be conscious of ever-changing technology and seemingly simple pieces of information that you never know when it will come in handy! That said, till the next time, maybe some of you would like to contribute some seemingly simple nuggets of information that you do not mind sharing with others. Do share with us at firstname.lastname@example.org soon!
Before I end off, here's also wishing Happy Lunar New Year to all whom are celebrating this early February (gong xi gong xi), and Happy Valentine's Day to those who still embraced the romantic notions of it. And, to be all encompassing for this quarter, Good Friday too! Well, no matter what is the occasion, do express your love for your family and loved ones. Even when there are no special occasions, I am sure one can always finds an excuse to show your affection to those that are dear to you. Not to be morbid, but there's nothing like the present. J
Happy New Year to all our fervent supporters out there! New year, new beginnings. Let us reflect on our past, strengthen our position for the present, and embrace the challenges that might appear in the future of 2008. A year older, hopefully wiser, 2008 looks to be busy and definitely full of new challenges for us at eLC, including yours truly.

What with interesting games, cute gifts & prizes, yummy popcorn & candy floss, self-moving balloons (yes it's not a typo error, the air current in our spacious ballroom actually makes the balloons float across the space randomly?!), and many more… Altogether, it was fun for our guests and supporters, not to mention enlightening for would-be participants whom are excited for the upcoming Competition that will be opened for application by June.
Our first overseas office @Subang, Malaysia
You heard it first right here! eLC will be opening up our first overseas office in Malaysia starting in February 2008. Who knows, it is the first step towards global expansion! Look out for more news in the same space in upcoming edition.
Title: Left/Right Brain and the Spinning Dancer
Active netizens might be familiar with one of the latest fads on the Internet today; looking at an animation of a spinning dancer and then deducing if the dancer is spinning clockwise or anti-clockwise. For those of you who have not seen this spinning dancer (or have not done the experiment), you should check it out at http://goohackle.com/right-brain-vs-left-brain-survey-poll-mind-optical-illusion/ before proceeding with the rest of this article.
Figure 1: A Still Frame of the Spinning Dancer
On the face of it, the experiment involving this spinning dancer is interesting. In merely a few seconds, simply by stating whether you perceive the dancer as spinning clockwise or anti-clockwise, your dominating brain hemisphere could be uncovered. Apparently, those who see the dancer as spinning in a clockwise direction are said to have a more dominating right-brain, whereas those who see the dancer as spinning in an anti-clockwise direction are said to have a more dominating left-brain.
A quick search on Google reveals over 180,000 sites mentioning or discussing this spinning dancer, including several thousand posts on Facebook , as well as a discussion by Professor Steven Levitt of the Freakonomics fame . The Internet abounds with various theories and comments about this spinning dancer. For example, some people stating that the spinning dancer does indeed provide good (and fast!) insight into whether someone is more of a left or right “brainer”, while others claim that the dancer is “programmed” to change directions and hence, is “rigged” and merely a joke. Others say that the perceived direction of spin is more closely related to left- or right-handedness, and yet others say that those who perceived the dancer as spinning anti-clockwise could actually be more “right- brainer”, while those who perceive the dancer as spinning clockwise are actually more “left-brainers” (and not the other way around). Yet others proclaim to be able to see the dancer spinning in both clockwise and anti-clockwise directions, while others insist that the dancer spins in one direction only.
All over an animated gif of a dancer who is supposedly spinning either clockwise or anti-clockwise!
In order to quickly check if the left/right brain theory of the spinning dancer holds any weight (or that the animation is simply a cleverly constructed optical illusion), a quasi-experiment involving two groups of 10 people was conducted. The quasi- experiment procedure (which took less than ten minutes to complete) went like this:
1. Each group was told to look at two concurrently running animations of the spinning dancer, which were placed side-by-side with each other. The spinning dancers were accessed from the same source (the animated gif file), but were unsynchronized in their movements due to the slightly different access time of starting the two animations
2. Each member of the group was told to report on whether they perceived the dancers were spinning in the same or different directions. If they saw the dancers spinning in the same direction, they reported on whether they perceived the dancer as spinning clockwise or anti-clockwise. They were given one minute to do this
3. After the initial reporting by the group, the two animations were closed, and after a few seconds, restarted again. Once again, due to the slight time variation in starting the animations, the dancers were unsynchronized in their movements
4. Step 2 was repeated
5. After reporting their observations, they briefly discussed their observations
The combined results of these two groups are provided below:
The first time the animation was played:
8 people saw the dancers moving in opposite directions
6 people saw the dancers moving in an anti-clockwise direction
6 people saw the dancers moving in a clockwise direction
The second time the animation was played:
11 people saw the dancers moving in opposite directions
5 people saw the dancers moving in an anti-clockwise direction
4 people saw the dancers moving an a clockwise direction
Out of the 20 people surveyed:
8 people reported that while “focusing on one dancer, the other dancer changed direction”
4 people reported that they consistently saw the dancers as moving in the same direction between the first and second viewing
5 people reported that for a moment, they saw at least one of the dancers change direction, but that change occurred only for a split second
The following are possible deductions we can make from this crude
Theory 1 (based on the assumption that the dancers' direction of spin provides insights to our dominating brain hemisphere)
About half of those sampled had equally dominating left/right brain hemispheres
About a quarter of those sampled were “left-brainers”
About a quarter of those sampled were “right-brainers”
Dominating brain hemispheres may be changed quickly and unknowingly
Theory 2 (based on the assumption that the animation of the spinning dancer is a cleverly constructed optical illusion)
The dancer would appear to spin either clockwise or anti-clockwise based on the amount (and location) of attention placed on the dancer
So, which sounds like a more plausible theory to you? Do you have a take on this matter? Email your comments and/or findings to firstname.lastname@example.org!
Title: Colour Modes - RGB vs CMYK!
Take a look at these 2 colours. Is there any difference?
They are both the same red colour. The left colour is brighter and more appealing. The left red is created using RGB, while the right one is created using CMYK. It may seem that RGB has got the upper hand. Let me introduce you to the interesting differences between these 2 colour modes, RGB and CMYK!
What is the difference between these 2, you may ask. Take a look at the 2 graphical representations for the 2 colour modes below.
RGB Colour Mode CMYK Colour Mode
RGB stands for Red, Green and Blue. It is the normal and default colour scheme used in computer graphics. As the computer screen displays light, when more colours are added, the lighter the resultant colour is, thus giving them the term “addictive.”
RGB can go up to 24-bit, with each colour channel taking up 8-bit. This figure is capable of displaying up to 16 millions of colours for your computer graphics. Isn't that powerful?
CMYK, on the other hand, stands for Cyan, Magenta, Yellow and Black. It is used mainly for colour printing such as posters, brochures and banners etc. This is mainly due to the reason that in real world, CMYK best matches the inks used for printing.
Referring to the colour model at the top, CMYK produces black when more colours are added. CMYK works in a way that is the direct opposite of RGB. It absorbs light when more colours are added. Therefore, the more colours added, the darker the resultant colour is. This gives them the term “subtractive.”
You may ask, since black is produced when all the colours are added together, why do we still need to include a “K (Black)” colour channel to it? The reason is simple. By mixing all the 3 colours, the black colour generated is unsatisfactory; therefore, black ink has to be included in.
In a nutshell, before creating an artwork, ask yourself this question:
Is this going to be printed out? Or is this going to be displayed only on the computer?
You wouldn't want to print an artwork only to find out that the colours are so way off from how it appears to be on your computer screen, would you?
Here's a summary of the characteristics of RGB and CMYK:
RGB (Red, Green, Blue)
CMYK (Cyan, Magenta, Yellow, Black)
Addictive colour model (Displays light)
Subtractive colour model (Absorbs light)
Up to 24-bit
Up to 32-bit
Let me ask the question again, is RGB still always the better choice?
