I made a terminal toy. It fills your screen with a grid of hex tokens that never move, and only the colors change: a curl-noise fluid field pushes blobs of red through the grid, and token pairs randomly flicker to new values like a live memory dump. It listens to system audio through PipeWire (bass/mid/treble via simple IIR filters, no FFT) and feeds that into the same fluid sim, so the music disturbs the liquid rather than driving an equalizer. 9 accent colors (keys 1-9), 3 visualizer modes, adjustable fluid/flicker speed pure C + ncurses, PipeWire optional one-line install, no root Repo: https://github.com/atif-1402/hextrix It's v1.0 so expect rough edges, especially the audio path on odd sample rates. CPU use is around 14% of a core at 60 FPS on a 200x50 terminal, so I'd run it at 30 if you're on weak hardware (-f 30). Feedback and bug reports welcome.   submitted by   /u/Desperate_Lion5740 [link]   [comments]
