Here's a short demo of an ASCII Tetris clone that I built in C with ncurses.

         To render the tetrominoes, I used half block ASCII characters and manipulation of background colors. Im really happy with how it ended up looking.

         It's missing a couple of canonical Tetris features (points system, slams, t-spins) but for running in my command line, I think it's kinda neat.

         Sticking with the theme of silly command line toys, this is an ASCII audio visualizer I built.

         This one also uses C-ncurses and I used Swift to tap the system audio. Thanks to DRM, I had to do some janky digital audio cable hijinks to make it all work.

         It pipes audio data (amplitudes) from Swift into a C program that performs a fourier transfrom (fftw) to get frequency data then renders it in ASCII block characters via ncurses.

         This last one is a game that my friend and I submitted to a game jam, and it's easily my favorite.

         We built it in Unity in 72 hours and I think it turned out pretty well. If nothing else, this one was the most fun to work on.
