Don't want to ask you your name or location to preserve privacy, but do you happen to live near what used to be a really cool coffee shop, and do you have an awesome garage with a plasma cutter? If so I think you told me about this project a decade ago while we built a little backyard forge!

Central Italy here, and no, unfortunately I never lived near a cool coffee shop and I never had a garage with a plasma cutter, but talked about the idea to some friends roughly in 2011 so it is possible that the word traveled around.

My buddy was working on exactly the same project around then in Austin tx. He was trying to make it as a web app with access to location permissions, where the page's background color would change for each individual pixel in the virtual display. Concertgoers would visit the url and their phone would become a pixel in the screen. He was trying to figure out how to get better location resolution when we talked about it, sounds like you guys had similar ideas and both discovered the implementation was trickier than it initially seemed it would be. I wonder how many other folks worked on that idea around that time?

Hi, I also had this idea circa 2014. I realized it wouldn't work accurately enough given the GPS limitations (and my limitations as a programmer) at the time. I pivoted to encoding color instructions in a high-frequency range of an audio signal emitted through the audio system of the stadium. I had a prototype working, but it was inconsistent and did not warrant a contract with the client. I've had the itch to complete this app since then.
