Well, I wanted gesture control but my IR censor wouldn't do that, so I ordered Gemini 335 from Orrbec. https://www.orbbec.com/products/stereo-vision-camera/gemini-335/

This will allow me to build a broad suite of AI-powered applications as well as just dumb applications that feel amazing.

For example, magic mirror, adaptive / spacial scenery, virtual teleportation... the list of possibilities is quite large! Should be coming in 4 days for me to play with!
