Bold CrossBar Plus Theme and Bold Today Plus Theme.
I bought both of these themes today ($6 a piece) from Gadget Bean, after watching the video of them in action on their website:
JC Designs Blackberry Themes
Take note; to all theme makers out there, video is much better than screen shots when trying to convey an example of your theme and how it looks and works.
Both of them are pretty cool, but I ended up going with the Bold CrossBar Plus theme because it gives me just a bit more screen real estate for my desktop picture.
I'm still waiting for someone to make a theme similar to these but allow you to scroll away both the Today section AND the icons at the bottom, or at least either or like on the old Today Zen Plus theme.
Good stuff though.
