I'd just like to add my Art Gallery Website to the collection here. It's called Phauxshow. We have over 200 artists and about 2500 images. The site is currently running Options and WP 2.7 - with some photo software for the gallery.
We should also have a bbPress live in a few weeks. I'm pretty proud of the project as it was my very first venture into web-anything.
Hope you like it!
Oh, and I love harsh, brutally honest and overly negative feedback (how else am I going to learn?) so don't hold back if you think something needs improvement!
