Here is a Zen plus Today theme I made which features a carbon fiber background and a yellow (Nextel) color theme. I hope you like it. It's my first try at a theme.
OTA (original): http://kjheu.kj.ohost.de/cy/com_plaz...bon_yellow.jad
OTA (updated):

Updated link above has larger font size and more Today items to fill screen.
Edit: I should add that the menus work for Bolt, Opera Mini, Etc.
