The weekend is here, and I’m sure you’re wondering how you can burn through hours and hours of your precious time by doing nothing productive. Like always, we’ve got you covered. Go download the free Phun program, and let your imagination run wild.

What is it? Phun is a 2D physics emulation application that will let you build simple or complex designs, and then watch them work. You can use boxes, circles, lines, and more to create geeky works of art. This video demonstration will give you a better idea of what I’m talking about:

Do all of those things look too simple? Then maybe you should try to tackle a bigger project by building an automated “machine” like this or this.

Learning the ins and outs of Phun might take a little time, but to get you started there are some tutorials you can follow. They walk you through how to build things like towers, cars, rockets, and more.

Go on… you didn’t have anything better to do this weekend anyway. Get Phun for Windows, Mac, or Linux
