It all started when I was backing up my WhatsApp messages and discovered that I had, for some reason, a video of my friend Matt repeating "this could be a web game". I can't recall the context, but it was clearly something to do with my habit of making stupid webby interactives. It turned out that I had a lot of portrait videos of Matt, so I stripped the audio from them all and made this silly tool. There's a couple of other people available too.
