Made with linear algebra, projects 16 4D vertices into 3D space and XW, YW, ZW uses matrix rotation .

Uses the CSG API to do solid Boolean subtraction.
Pretty hard. Live geometry cutting. It uses triangle-plane clipping, concave mesh splitting, and has polygon ear-clipping so no hollow areas appear.
This uses a state-history recording ring buffer. Changes the part's unanchored assembly linear/angular velocities to rewind their position history.
Spring-mass soft-body physics. It has some butterehh smoooth jello bounce, and uses a custom spring solver. Made the model in Blender as a complete newbie.
