Moose dropped on a simple mathematical function (plus annoying bugs)

The moose series never ends, apparently. This time it continues with 5000 randomly distributed point masses confined to the interior of a moose-shaped contour, the points being released under gravity and falling on the function f(x) = abs(x). This is a non-chaotic system but the points spread out linearly over time and eventually reveals a shockingly nimble moose. The bug in this system still bugs me. On rare events a ball or two decide to take a non-physical path. Music: Gravity_Y by @gpcbass. Used before here. Visuals in Python and FFmpeg.
