If there's anything that screams insane more than this DHTML version of the original Lemmings, I don't know what the hell it could be. The author, "crisp", must certainly have a lot of spare time on his hands. He has meticulously recreated the original Lemmings game in javascript, of all the stupid languages to use. Not that I have anything against javascript, it's just that, well, its probably the least appropriate language I could think of to do this in.

Stupid or not, this is nonetheless an incredibly ambitious project, and it's nearly flawless. He's recreated the exact gameplay and graphics, along with 40 levels. Ten points for dedication there...
