Phun, as entertaining as the name suggests

I found out about phun a good while ago. But it's only once in a while that I actually get to play it again because I always try rather big and unpredictable experiments (that's why I like portable apps!) so programs only keep if they are any good, because I'll only actually bother to get em back if they were any good!

Anyway, so what am I talking about? It's a 2D physics sandbox that is extremely addictive! You can invent something to do anything of nothing, except maybe something that's important! In simple terms, it's a program where you can build thing, press play and the objects that you place will move into action(e.g. if you put a ball in mid air and pressed play it would fall).

It's not open source, but it's free and build for Linux, Mac, and PC(notice the order), the Linux version runs dead slow so I use wine and run the windows version(bizarre, isn't it!).

If you have any interest in physics(or Phun) or just something creative, try this.
