I played the old Powder Toy. I actually had an account but never really published much. I was always the best person in my class (everyone played it) at it, after a while the servers stopped working at school, but it was just the firewall. Not much after that they were broken everywhere, powder was dead. I actually found the new one at a LAN party, somebody wanted a powder download, so I just told them to search for it, expecting them to get the geeks 3d one or something. They downloaded some crazy powder toy with the elements on the side, and an insane number of new things. Needless to say I was shocked and proceeded to download it.
Another thing is for a while after the crash I had the only downloads of powder toy available for Mac and Linux, and might still have the only old powder downloads for them.
