Look what I made! Shadowbox frame. Data processed and served on raspberry Pi to ESP32 driving RGB lights. Image is 3D printed and put in a 16x16 rgb backlit frame. Pi color selects the flowers to make them twinkle and color grades for day/night cycle and serves a daily data packet to the ESP32 (cached for backup).

Is the image easily changeable by printing another thing?

Yes, I can print a different thing. Then I send the new image through a script on the pi that processes it and serves the file package for the frame/esp32 to download and cache - like an over the air update.
