Thanks for letting me know about people using the gallery feature like that - it's the kind of story that we remember!
The creative way people use very simple features to build new experiences is the kind of "aha" moment I want to make possible with Touchgram - https://www.touchgram.com/ .
I'm not (just) targeting memes. It's a convenient example of the many popular things people consume which are almost-always static experiences - you sit and watch something, rather than being able to interact with it.
