Friends in the D&D group showed me this.
http://powdertoy.co.uk/The Powder Toy, misleading name but basically it's a physics tool. It has all kinds of things from negative gravity, to black and white holes, periodic elements, and several other things. Create, concoct, mix, explode. The tool is a dream for people that like to mess all of that.
Posting it here because it'd probably be VERY useful for anyone that wants to experiment and come up with tech ideas through it or wants to see how others tech works... All in all, it's extremely fun and useful.
Steven and Chase, the two that showed me it broke the laws of physics and created a Perpetual Energy Anti-Gravity Machine from just experimenting around with diamond,and a fission/fusion plasma reactor fueled by noble gas and a few other things. (surprisingly NOT negative gravity) The result was this huge orb that never loses energy, never burns out, and repels EVERYTHING away from it O.o it is completely indestructible.
You can even create a planet and life in this thing if you mix the right things and work with it long enough.
But anyways, yeah. People like Orph ...and Gaser... and others will probably find it useful. I did!
