It's silly, but it's phun!

Some lunaticEmil Ernerfeldt at Umeå University (we hang out in the same IRC channel) has created the game2d physics sandbox Phun, and the introduction video for it says it all. I once heard my nephew speak about building an automatic popcorn popper involving a conveyor belt through an oven and a robotic hand to put the popped corn into a bowl - I wonder what Phun would become in his hands. You can download it here. I don't dare to try it, I will get addicted, I'll just stick to Transport Tycoon when I need my fix.

PS. Unless I manage to pry my PS2 back from the hands of my other nephew and niece...

(Update: Now we're just wanting programmable PID-controller functions, then it could be cool to be able to script things like you do in Colobot. Please?)

(Update 2: While I'm at it, let's suggest games like Totem Destroyer and the Orisinal games. Happy waste of time :-P )
