I could *not* look away from that spiral. Mesmerizing.......... (eyes glazed over staring at screen....)

In other news -- note to self -- deal more gracefully with lag in the update.

No worries... life gets in the way sometimes. I'm just glad you built something that I can play around with. :D (Imagine that spiral with different colors or velocity-sensitive line brightness/saturation)

Colors dependent upon velocity? That would be awesome! We could also have colors dependent upon acceleration, or distance to the closest object, or probability of the planet supporting life, or... I'm getting carried away... :P

oooo. hue dependent on proximity to another body! I could do some pretty cool stuff with that!

Either based on "attraction" or distance, as one body gets closer to another body, it turns blue (or one hue) the further away it gets from any body it turns red (or another hue). If you combine that with "brightness" or saturation based on the velocity of the body (i.e. the faster a body goes, the lighter or whiter it gets -- the slower it goes the darker or more saturated it gets) -- something like that.

Oh, and here's something even cooler:
-Mass or velocity or the acceleration of any object or the gravitational constant or force law changing based on the distance between two bodies, the acceleration of a body, the gravitational force acting on a body, the velocity of a body, the area or perimeter of the triangle made by three bodies, the... oh, woops, getting carried away again.
-OH, we could have hyperbolic geometry in the gravity simulator to represent the hyperbolic geometry in Einstein's theory of general relativity!!! We could also have circular geometry, or cubic geometry, or it could be so many other geometries, except I can't think of any off the top of my head.

Uh oh, exfret is overclocking again!

Interesting stuff with color changing. I'd like to give the planets selectable colors ("this one will be red, this one green")... which might not work perfectly with this idea. But maybe I could make it a toggle on/off option.
