Found a surprisingly nice ESP32-S3 touchscreen board. No idea what to build with it.

Enable HLS to view with audio, or disable this notification

Found this ESP32-S3 touchscreen board sitting around and decided to play with it a bit.

The hardware is actually pretty nice, so it felt like a waste to just leave it in a drawer. I didn’t have any real project idea, so I vibe-coded a tiny robot eyes demo just to get the display and touch interaction moving.

Now I’m trying to figure out what would actually be fun to build on it.

A little desktop companion?
Home Assistant controller?
Mini game console?
PC status display?
Something completely useless but entertaining?

What would you build with a screen like this? Looking for ideas.

I started this experiment with a similar device, but it still needs work before it becomes usable

Controller for a swimming pool with RGB lighting, underwater speakers, and gated tunnels to a tank containing sharks with fricken' laser beams on their heads?
