If you know any good game/challenge style galleries, let me know! I remember an old gallery where you had to complete a certain number of strokes per picture with the gallery on a 10 second slideshow, but that one seems to be gone, and searching for anything like "fap challenge" brings up a lot of other content too. If you read this and are in the business of creating galleries, feel free to hit me up to see if there's things we can do for one another.
