Classic free physics sandbox game The Powder Toy is now on Steam

Remember when falling sand on your screen was all the rage? The Powder Toy is a classic physics sandbox game, which simulates air pressure and velocity, heat, gravity and a countless number of interactions.

It's free and open source, with a pretty active community around it and a lot of fans and now it's been released on Steam too. Making it easier than ever to mess with physics and just — see what happens. It has Native Linux support and my test of the Steam release showed it working fine on Kubuntu 24.04.
