Author here. Glad to see this making the rounds again after a few years.

Great education simulation! Thanks for working on this.

Curious about this: I am hitting a boundary-condition like behavior drawing a straight line at a 45 degree angle similar to the sibling comment.

Curious if it is due to physics or due to the simulation.

I am pretty sure it's the simulation.

This is very cool.

I found shapes that do not work well with the simulation: a very wide and narrow shape (like a needle) oscillates wildly and does not seem to stop or to even slow down.

You have possibly unlocked the secret to infinite energy.

what do you expect instead?

nice job. these simulations are 2d. does 3d make a difference? i'm almost about to start carving styrofoam to see.
