It looks like Algodoo but less fancy http://www.incredibots.com/index.php I was just browsing a forum and I found this

I've known about this for some years, it came out after Phun so Emil couldn't copy it!
Incredibots looks very limited and boring to me, nothing beats Phun/Algodoo

Interesting. But as Lucas said, it's probably not as good as Algodoo, so that's what I'm going to stick with.
