marc100 I'm not expecting you to count the number, but here's a pretty good resource for themes:
Aside from a tonne of other information, the site is continually updated. It basically links you direct to the author of theme, ensuring you're not getting an old release.
There's a lot of other things you may want to take a look at there too.
As Root says, you can take a look at his templates, and they're very easy to get to grips with - I'm not expert on CSS but I like his work.
Hope that helps and good luck
Also if you find a theme you like and as you say you want with no pictures, I think you'll find many here can help you in removing anything you find clutter to make it a cleaner theme. So if you find one you like but it has a lot of images, just ask for assistance on that theme and it can be dealt with.
