Same talk as my (US) GDC talk btw, but without the paywall 😉

Because I'm a completionist

Prices in my screenshot are in Australian dollars

The led frame itself is made out of four ws2812b panels, a 3d printed grid and a sheet of clear poly carbonate that I spray painted with privacy frost effect paint. The effect is hard to capture, but looks a bit like neon tubes if they were pixels. There is a warm glow and brighter middle.

And it's a bit of a wood working/machining project as well. I used my CNC to build the frames and cover plates. Last pic is the mini PC powering it

The first game I made for it is a 2 player dungeon crawler where you need to collect all rainbows. One player walks, the other shoots and each time you pickup a rainbow, your controls switch over.
Also notice the ammo counter on the arcade stick itself, also ws2812b leds (this time over serial)
