Via the "ExpertZone" blog, a post over at Pro-Networks talks about this:
Lemmings, a DOS pc-game
Some enthousiast PCusers out of Holland have made a DHTML version of it. Even the old sound is included.

This is just too cool! I used to spend hours on end playing this game... absolutely LOVED it! I guess i'm kind of a puzzle-a-holic. I love challenges and solving problems... which explains why I'm a software developer, too. :)
