Thanks. Very fun to try to make unique patterns.
And with the new version of Universe Sandbox that's in the works... You'll have better (and more obvious) tools that will make simulations like this even easier to create.
In fact... The next release will be the first time that Universe Sandbox will have an adequate toolbox for controlling the simulation unfolding in front of you. I can't wait to share it with everyone.
Didn't think it would be this popular! =P
That because it's awesome.
(although that claim comes with obvious bias)
And personally... the video was extremely satisfying to watch. It's very humbling to watch videos of Universe Sandbox created by people other than me.
