Moose dropped on a parabola @animations

Uploaded March 2024 | Updated September 2026, 2 weeks ago

3000 randomly distributed point masses initialized to be confined to the interior of a moose-shaped contour are released under gravity to scatter off the function f(x) = x^2. As with the function f(x) = |x|, this is also a non-chaotic system and the points spread out linearly over time and render a rather interesting transformation of the moose points.

The bug in this system will never be resolved. Here a single annoying ball suddenly decides to take a strange non-physical path.
