I don't mean to plug my blog (okay, I do), but I already posted this there, and didn't want to duplicate it...

I just got a second-hand Cowon iAUDIO T2 DAP (hey - it plays OGG!), and was fiddling with the on-device "screensaver". As mentioned in my blog post, the resolution of the so-called "screensaver" is deplorable, despite the device clearly being made to handle much better graphics (see comments on start-up splash). I haven't had time to poke around much more than I mentioned there, so I thought I'd leave a note here in case someone else had a T2, and knew anything I didn't. I wasn't able to find much Linux-related info on it aside from the company's site stating that it was compatible, and the only easy way to make your own graphics for it is a proprietary, Windows-only app that does that as a side-feature.
Anyhow, if anyone finds out anything interesting to do with fiddline with the graphics, config, or anything else about this device, let me know...
