Once you have a Jailbroken iOS device, you can download a theming engine called ANEMONE, which allows for HTML to be used a wallpaper etc..
Which then opens up a load of possibilities for using CODEF to make iOS wallpaper!
Tonight we have a cool effect called "PHIreworks", running in CODEF, on my iPhone 6 as a wallpaper.
I have posted the video below, but in case it doesn't work on your browser, you can download a sample video from the link below.
I also used CODEF to make an oldschool tunnel effect, which you can see at the Facebook CODEF group. Link below... https://www.facebook.com/groups/codef/permalink/1037938472974147/
