Via http://images.google.com/images?hl=e...=hp&q=3200x480 will also find pictures sooner or later although right now I didn't see many. (Actually, you can see one guy having a project using 4 laptops to project a 3200x480 wide screen on a festival, and you also see kontorii's blog with post about his theme maker. Pretty cool... ). You can then split these 3200x480 in 4 parts. Only problem is that (usually) the 4th part doesn't connect with the 1st part. To make cool backgrounds which do have 4th part connected with 1st would require a 360 degrees photograph!

Moving background like in E71 would also be neat. Even though it renders very well (better than X) it'd still be too bad for the battery though.
