XDA forum member marc22 saw a picture of the Cowon D3 Android MP3 player, liked the clock and posted a request thread for someone to build the widget.
The first member to have a go successfully was XDA member rsmartin. The dev spent an evening playing around with the Android widget API and built a clock widget in the style of the Cowon D3. Not only that but he built a collection of widgets in that style. Confirmed to be working on the Desire and Dream.
For those of you interested in developing a widget yourselves, the XDA dev has helpfully posted the source code on github.
Head on over to the application thread to download the apks and the link to the source code._________
