Sorting UI

Screen-horked in it's true CSS glory from Chrome.
The markup is so stupidly simple it makes me smile (a UL, LIs, and a class for up or down. That's it.).

And, No - you don't see up two items at once. I'm just showing the two states possible. It does use and image for the triangles. I could roll those in CSS too, but we have a pretty heavy user base in IE - AND we already have a sprite-sheet. So...diminishing returns...

Feedback always welcomed...unless it's OMGWHYISN'TITFLAT!!! ;P
