Simon wrote a Tetris program in Processing (Java) on Thursday afternoon. He has never played Tetris. He learned about the game from a Russian educative cartoon series Fixiki episode, where it was briefly mentioned, and he used a YouTube thumbnail picture to help him design the shapes and the colours of the pieces. The project isn’t finished. Simon got as far as having the particles fall till the bottom of the canvas and being able to move them to the right and to the left.
