Elysia and Val kindly pointed me at Oracul when I complimented them on their wonderful standing animations, and now I have one of Oracul's AOs.
I'm still getting used to it. The animations are graceful and fluid (yet another reason to favor fps a bit more when I'm not taking pictures), but I feel a little fidgety.
UPDATE: Thinking about animations reminds me of a pet peeve from the past: a sitting animation for women that made one loop through a rapt contemplation of one's fingernails. Oh, how I hated it! Earth to whoever the animator was: there are intelligent women out there.
UPDATE: The fun part is going to be figuring out the documentation.
