Theme Creator?
 

Does anyone know of a program that will help me create my own themes?

Search for:
Thememaker McDeb
Theme Builder
ThemeMaker

Just google something like "ppc theme maker", "treo theme maker", etc...you get the idea. I don't have anything handy right now...but just poke around.
Later,
Coz

im currently using the thememaker mcdeb that supports square(240x240) themes and its actually pretty neato in conjunction with the ui tweaker.

i would have to say there really isnt that great of a theme creator yet for wm5, usually u need to finish tweaking with UI Tweaker or Tweaks2k2

look for themegence. you can use it for WM5, including adding pictures for portrait and landscape and custom colors. I was able to make a true black top and bottom bar, and and have a working landscape background. and its free.

You mean something like this:

all black theme is already available and you tweak it UITweaker.

exactly, but that looks like it was made for a square screen. on something like the 6700, it is hard to find a theme that has decent landscape support. using themegence, you can get it (and the wm5 colors).
