Hmm...
Well, the animation thing and ray casting are nice (if, like everything, incredibly overdue) but there's not much else, really. Guess LL knows it's audience and it's not me. Pity, really; despite some questionable architectural decisions, it showed a lot of promise back in the day and there's still little alternative. At least the net code felt tighter when I logged in.
Well, maybe I'll pop back again in a few more years.
