@dumpsterqueer@ondergrond.org this reminds me of my very favorite defcon thing ever.

Someone made a hat that hosted its own network and served up a little image board. The hat was huge and lit up. Hard to miss. Whenever you were in the same room as hat-chan, you could log on to the image board via a smart phone and shitpost about the talk you were in.

It was incredible.

IMO, it's not super future far fetched, it's feasible today. The localization of the network was a big perk, as was the ephemerality of the whole thing. People wouldn't post contact details, but they would say stuff like 'I'm the girl in the blue shirt sitting in the second row, let's meet up at the bar after this talk'.

And yeah, people were actually pretty cool to each other on it.
