Behold the world generation saga. My attempts at generating nice looking terrain range from incredibly dubious to slightly convincing.
Conway's Game of Life - a zero-player cellular automaton made by mathematician John Conway
Raycaster - a 2.5D implementation of ray casting
Maze Generator - a maze generation algorithm that I made
Collision Demo - just a 2D movement test with camera movement
1D Terrain Generator - a terrain generator that uses midpoint displacement
Aaronson Oracle - a very basic and crude machine learning algorithm that predicts key inputs (a much better implementation by Adam Pearce)
Bézier Curves - A small bézier curve demo where you can make n-order bezier curves
