This "addicting" game has been here for a while, but it seems that I've just noticed it recently. If you're getting bored of doing "work", you're free to check out this game by Coca-Cola.
I don't see any reason why they would have created this, as it doesn't relate to anything they make, but I can see this as a marketing tool designed to attract children to know their brand-name (like they don't already!)
Anyways, it's this "sticky hand", if you remember those made from silicon that seem to stick to walls, except in this game, it sticks to your browser window!
