the first time I saw this effect (in 2004), it was done was by @trevorjofficial, for the album cover of "Any minute now" by Belgian band Soulwax. https://t.co/rYcjo0q46o

I can tell you that this illusion has been around for at least two decades. Here's an image that was widely published in the UK in an "alternate-reality-game" back in either 2003 or 2004 (Explaining perplexcity would take many tweets, but tldr: this was presented as a "puzzle") pic.twitter.com/4ihvo4v1gy
