Learn about the rabbithole of LEDs, how it went from a single tri-color LED on my first OHMC project, to a "it was only there because LEDs are bling" neopixel ring on garduino, to a "few" LEDs on my party shirt, and then shirt and pants, to "it's gotten out of hands", a 1538 pixels on panels driven by ESP8266, then 12288 pixels driven by ESP32, and now 49152 pxels driven by a raspberry pi. Amazingly the last 3 projects, despite using very different hardware, use the same codebase and graphics library I wrote, Framebuffer::GFX.
