The earlier versions of this had the brackets do a cool spin so that they could rotate around an inconveniently placed arm. Alas, no more of that. Finished this particular solution on either Friday or Saturday, and (considering this one's submission date is Monday night) I have realized that I should submit now before I forget forever. Probably will give latency a shot, but we'll see. Or, I suppose, since I think latency gets shown first, you'll already have seen.
