Wait for epoch (Time on the clock) to be 60.
The planet with a circular orbit will appear at that time, click on it and click 'ptolemy', for a weird orbit-shape from the planet with the eccentric orbit!
Holy crap.

That's like, all I have to say. Great job mate.

Load, then look at the right edge of the screen. A box, open to the left, should slowly appear. After it does, wait a second, and something should happen. Once it does, pause the game so you have time to check things out.

Goes to about t=1550 before messing up. It doesn't actually collide, but something happens.

Doesn't seem to mess up for me.

It does however "collide" (More like bounce around/go off into infinity) at epoch=4000.

Had a moment where I thought "what the heck does AG mean? The sim is in 2d... you can't have a 2d slice of 1d space"

But, of course, you *can* have a 1d slide of 2d space. Neat to watch it, especially knowing that it's literally what gravity would be like in 1d. Seems pretty gentle, I must say. Some clumping here and there, but never strong.
