If you haven’t already, check out the CameraBag application for the iPhone. It allows you to apply a nifty set of features to photos on your phone.
Of course, because [Django](http://www.djangoproject.com/) is awesome, and because [magical ponies](http://djangopony.com/) are even more awesome, I ran the [DjangoPony for iPhone](http://dl-client.getdropbox.com/u/10320/django/wallpaper/magic-django-pony-iphone.html) wallpaper through CameraBag’s “Helga” filter.
The end result is a really nice wallpaper for your phone.
