iPhone business idea

I stumbled across these web sites recently. Poolga let's you pick artistic wallpapers for your iPhone, Tseventy gives a collection of hand-picked photography that you can download to your iPhone. Strange that all images seem to be portrait though.

The iPhone opening screen is a waste of screen real estate. Why not have a new image everyday, a useful quote or an interesting stat, or a word of the day? We need a (presentation) designer and an iPhone app programmer to get together...

It reminds me a bit of the early 1990s when Internet-powered screen savers clogged up corporate networks (remember Pointcast?). Leaving network performance aside, it did not work for desktop screens because people are staring all day at these. The mobile screen in your pocket might just be suited though.
