One of the rules that I live by is "if you're going to make a fool of yourself, it's best to do it wearing a sharp suit and a pair of illuminated goggles". Actually it's a rule that I've just made up for today. But it definitely fits the bill.
I was part of a presentation from 2042 that c4di put on as part of the Substance element of the Hull City of Culture celebrations. I figured that, since 25 years ago people were still wearing suits, they'll probably still be wearing them in 25 years time. And the goggles? Well, let's just say I had a pair of neopixel rings free and an Arduino Pro-mini lying around. And this article from Adafruit to follow.
The brief was to deliver a technical session from the future. We were allowed to make things up (this seemed the easiest way to do it). I made up an operating system, called HULLOS, that runs on the entire city of Hull. I had four minutes to fill, so I went through four versions of the operating system in the years that lead up to 2042.
There was the Base Version, the VR version, the Freedom version and finally the Sentient Version. I provided an appropriate amount of hyperbole, with newly liberated artificially intelligent robot refuse collectors discovering a shared passion for "Strictly Cart Dancing" and an air of arrogant omniscience, "If you're the smartest person in the room it means that I've not arrived yet", which is quite unlike me. I even took a 360 degree picture from the stage in the middle.
