Theme Showcase?

I am new to WPMU but not at all new to regular WordPress. I am now playing with Nelo and Triden themes trying to decide which one I will use for my site. Other than the screen shots provided, is there a showcase available of how the Dixi, Triden & Nelo themes are being used (to provide some creative synergy)? I am having a really difficult time trying to come up with something unique.

Any links or suggestions?
