sandbox games are amazing for this. Can't wait until we get a real serious 3D physics sandbox and faster computers where we can simulate massive amounts of particles, things will get really interesting.
If TPT was recoded, massively updated and generously funded, as well as run in supercomputers and benefitting from a large community of experts, the outcomes would be amazing. If 'ordinary' guys (still amazing) like Cracker-64 and his team, together with our community, managed to do amazing things in here and discover so many interesting phenomena, imagine what could happen if things were like what I described? TPT is a masterpiece.
