I was somewhat hoping it would "crystalize" into a lattice, but it wouldn't work since energy is conserved in the sim.

Things to try:
Fling a heavy planet into the box (It'll probably exit due to conservation of energy)
Put a heavy planet into the box
Fling/put a heavy negative planet into the box.
Make a heavy/heavy negative planet go in a circle in the box. With a heavy negative I got something that looked like the clouds at L4/5 (but only one). This is entirely different though.

I noticed the posting thing. I can assure you though, I got something good brewing.

As for your systems, daaang son.

One question though: how do you manage to copy the things from output? For me printed things come out on the console so I can't copy them. Do you use ironpython or whatever it is or something?

No one's posting because I'm not posting. I know it's due to other things too, but I'm sure that that's a big part. Of course, if I had been posting you can't say no one's been posting, anyways.

Darn you, conservation of energy! Cool how those negative mass planets really resemble a gas of atoms in a box. Random bouncing motion and everything.

Also, might be the first python-ed codes for the GSim, eh? Awesome milestone for it, then!

As for not posting much... it seems that posting begets posting... seeing as we all popped outta the woodwork here

I've been splitting my time working on two new updates (so that I'll have cool stuff to post about!) One is the next less-buggy more-feature-y version of this Simulator. It's been a trick catching up with all those bug reports, let alone adding new stuff. But I'll put up a version this weekend.

And the other is a new game I've been working on... nothing big, but I'll be interested in some feedback from you all.
