I use the pineapple for nyan-catting as well! I've been doing it since the Mark II. Nothing quite as fun as hearing that song blasting from all over the Panera. Anyway, I created a full page scrape using chrome and modified it to work the way it should on the pineapple. I have included a link below. Functions identically to the actual website.
non-stop nyan (7-zip file) (This link should be a public link, please inform me if it is non-functional, thanks.)
Long time Pineapple user/forum lurker. This post made me come out of hiding. Enjoy!
