I like what's possible with triangles.
Playing with rectangular blinky grids is super fun, and I've made a weather monitor and a pulse-oximeter with those.
But there's something additionally awesome about the pattern possibilities with triangle pixels.
So when I saw a Hackaday post about building a clock display with LED triangles, I was hooked.
The short story is that I made it! It now lights up my living room with dazzling animations and a funky time display.
The longer story involves perseverance made possible by my coronavirus lockdown.
