Update 2025: 
I am still working on this! Now works on ESP32 - and the new version is getting close to actual PRODUCTION (Magic Poi). The new version has a web app with image sharing to multiple internet connected poi.
I have a Patreon account now where I share updates - as well as the usual Blog and Tutorial on the circusscientist website. https://www.patreon.com/c/CircusScientist
