This is a 20x40 pixel LED display I constructed from addressable LED strips. I started this project a long time ago, when I was in highschool, and haven't made any changes to the hardware recently other than repairs. Lately, I have been working on the software side. I re-wrote the control software in Rust and have been adding more patterns over time.

Below is a demo of it running the control software which has been compiled to WASM. The real display is configured to turn on once a day at sunset and run only a single pattern for that day. It will turn off again 3 hours after sunset.
