N body gravity sim with rust and ggez, made to learn rust
Initially written with OOP, made a new version with specs that runs about 20% better on my desktop PC, but slightly worse on my laptop. Maybe because it parallelizes a lot more?
Web port made with quicksilver, lots of features missing:

Arrow keys to move
Scroll to zoom in/out
Q/A to increase/decrease radius of next placed body
W/S to increase/decrease density (try making it negative)
E/D to increase/decrease trail length (removing trails increases performance by a lot)
X/Z to increase/decrease prediction speed, setting it to 0 turns of predictions.
Left click to place a body, dragging before releasing makes an initial velocity vector.
Right click over a body to delete it.
G creates a 10x10 grid of bodies with the specified radii and densities.
R to reset.
