got an idea you may want to try. i don't know if it's possible (i never tried to do a rotating cube) but add a 7th picture saying something like how did this get 7 sides or something like that so people will keep watching it to count the sides. if it is possible one place to do it would be to change the bad luck brian meme when the cat is the main focal point to the 7th image. but yet again i have no clue if that is possible
