If you have been studying physics or similar, you know that it can sometimes be hard to visualize how a system will behave. Even in classical mechanics, which is probably the field where our intuition can help us the most, it would sometimes be nice to be able to draw everything on a computer, and turn on gravity or other physical effects to see what happens. I know I thought a lot about that.

Well, just recently I found a program that can do just this. I could go on and tell you everything about it, but just take a look at this video and see for yourself. It can simulate gravity, friction, motors, liquids and a lot of other things.

It’s called Phun, and it’s fun as hell. It comes for Linux as well as Windows, with Mac support coming soon. If you want to see all the crazy things people have been doing with this software, go to their webpage or do a Youtube search for Phun.

And if you make something cool with it, which we’re pretty sure you will, send the file to us and we’ll rate the coolness of it, and bring the results in a post.

And oh, you can download it from here.
