Gravity Trails

This code is terribly simple, but hypnotic. 4 particles are created in 3-D space (the visualization is a 2-D projection), and all interact gravitationally (using the traer physics library) with one another. Each particle traces out a coloured trail, and each is connected to all the rest by a straight line. Simple, but the end results are beautiful:

This is an earlier version, 10 particles in 2-D, with only the particles tracing out paths. Also pretty:

So awesome. Is that entirely mathematical? I'd love to try and modify it and use it for a game background. I'm not sure what kind of effect it has on the resources.

Would it be possible to have the game input effect the parameters of the trails? So say you're doing poorly the trails slow and become colourless.

Seems so perfect.

Yes, they're both completely physical and mathematical. The only random element is the initial position and velocity of the particles (and the colours).

I don't know how resource intensive it is. I used the Traer physics package, but it could probably be rewritten from scratch for this particular, simplified task.

Making any of the parameters dependent on some external factor would be pretty easy to do.

nice, hope I get the time to understand it.

Really nice!
I made something similar a while ago, with user interaction:

But yours was very nice indeed Smiley
