Colourshift

I have found the most addicting/fun/challenging puzzle game on the internet. Well not really, but it is a great game. It's called Colourshift (link here), and is a cool flash game where you have to connect sources of light to the appropriately colored light bulb. It's easy to learn, but impossible to stop playing. I play a lot of online flash games in class, so I wouldn't recommend this to you if it weren't good. Don't forget that I was the first person to recommend Bubble Spinner last semester.
