I'm trying to find this electronics youtube channel where this guy makes these low-memory devices to hand out to everyone at some kind of yearly con. He does something different with them each year (I think). One year he got them to display an AR-ish wire-frame layout of the building the con was held in and it displayed other people holding their devices as little wire-frame ships or orbs or something (I think) and you could shoot at them and it looked really cool. Another year he managed to integrate VR-Chat with this somehow. He did other shit too but that's mostly what I remember. Does anyone know who I'm talking about?
