With that out of the way here's some more ridiculous stuff:
In 2016, I made a browser based AR party game where you'd fight kittens falling from the sky by dancing with vegetables in your hands (CMYK was easier to track using the webcam). I have some photos here: https://goo.gl/photos/g6Dp8GLDbuuhT1TRA
From a technical PoV it was exciting (running AR, in a browser, in pre Pokemon GO, pre WASM times!)
I also made a simple photography lighting tool, replacing professional lights with computer/tablet/phone screens (facade.photo). I put it in an old wardrobe bought in a thrift store on Brick Lane and during my startup launch. Results: https://goo.gl/photos/RZ3fCRcScYSGr7aG6
Ah, I also made an AI-powered voice assistant in 2014. The tagline was HTML5-powered voice assistant, as AI wasn't really _the_ buzzword then, but _HTML5_... oh yeah.
