Lemmings is probably one of the most popular games of all time, and to see it implemented entirely in Javascript is pretty amazing. The fact that it is a perfect reimplementation of the original is that much better. This site has been around now for years, but that doesn't make it any less cool.

If you're not familiar with the game, the concept behind Lemmings is that you get a bunch of little guys that are released at a steady rate, and you need to get them to their goal. You have palette of different skills that you can give to your lemmings at any given time, such as digging, building stairways, parachuting and even exploding, and giving the right attribute to the right lemming at the right time is crucial to your success.

For a walk down memory lane, and a very fun time waster, check out DHTML Lemmings.
