A minimalistic implementation of the Julia iterated Fractal here.
It uses only characters to "draw" the fractal, it is quite responsive on Chrome and it allows zoomming in and out.
Also it does not use any external library.
Maze-generation experiments: here.
It uses "moles" (ant-like automata) to draw the roads, cellular automata for the terrain generation, and Wang tiles.
First chapter translated into Italian: here (Ho iniziato la traduzione in Italiano del libro di matematica)
PWA experiment 1D Soko. This game is a 2K JS game, with procedural graphics, and it got 10th price in the game jam 2kplus-jam (out of 20 games :D :D ).
To play on your phone: touch the screen on the left to move left, right to move right and in the center to fold/unfold the level ;)
