PixelPhones
summary
Browser and native builds use OpenFrameworks C++ app and web sockets handshake to locate and time‑sync phones by averaging round trip times then scheduling future timestamps, cameras read Manchester-encoded flashes from each screen to map IDs to positions, Wi‑Fi is the bottleneck, prototype finds a few hundred phones at once (claims ~360), runs demos like Nyan Cat and Simon with mixed reliability, and the code and assets are planned to be released open source for larger scale work.
