There is a large collection of gifs based on the reverse phi illusion in a tiny obscure subreddit that I unfortunately can't find again. I think most of the submissions were made by a handful of users and they never referred to the effect by name. It was mostly artistic applications such as an angel infinitely rising upwards just by flashing two images. If someone finds it again, please let me know!
I too tried to find a few collections I've come across, but no luck... not too sure of what search terms to use. Was hoping someone else would come in clutch.
