Thanks to dsp and the bug this thread placed in my ear, I've been doing my own messing around.

Here's my main activity display:



The background is below (it's a 176x200 cell phone background ... you can find them all over the place). I was looking for something a little different (in keeping with the "Johnny Canuck" theme ...):



I made the buttons using Paint.NET and created custom icons for the PS3, the Xbox 360, my HTPC (it uses MediaPortal as the front end, so I used MP's icon), and my HD DVD player.

The pics show a little grain, but it can't be seen on the remote itself.
