Nyan Cat / Pop Tart Cat, the original creation of LOL-COMICS / Chris Torres / PRGuitarman, alive and on your Android's wallpaper. Hooray!
This is not an "app" but will install the live wallpaper, which can be chosen from your live wallpaper chooser (home screen > menu > live wallpaper > look for pop tart cat, click on it, then click on settings.) The limitations of this app and the script do not allow the background to stretch across multiple homescreens or turn to landscape mode. There's another "officially endorsed" live wallpaper that might stretch and go into landscape mode and stuff; I haven't tried it yet, but it's $.99 and you can find it pretty easily by searching for [Galactic] Nyan Cat.
Thanks to Andrew121, Daneshm90, Mrdaviso on xda for the work on the original app and the scripts to make it customizable!
And thanks to Chris Torres for giving me his blessing to put this free wallpaper up and his efforts to bring us back after they tried to shut us down!
