It took a surprising amount of effort to achieve this crappy result. It's rendering 4000 views simultaneously per frame (effectively 120000 fps), on a Pi 4. Complicated by no viewport arrays or layered rendering support, and clipping in the fragment shader added seconds to render time.

People watch my videos and think, well this guy's clearly an idiot.

Back when the web was just the web, I would occasionally make unexpectedly popular Content, and it was fun to look through the referrer logs, see where people were coming from, browse around in those communities and so on. With the youtube stuff, 'external' is only ever a few percent, and within that it's basically 'discord' which could be anything. But it's still quite fun seeing little clusters of comments from people with the same angle on it, and trying to work out their thing.

I switched to a 0.2 mm nozzle and had another go at the diffuser for this led matrix. It works really well - the front is a single layer, and behind that is exposed infill with the same pitch as the panel.
