The contest isn't over just yet. I'll still be accepting entries for another half-hour.
I'm just posting now to make clear that I won't be able to finish judging until all the entries are in (I've received 60 so far!), and the winners won't be announced for another hour or so after that. Y'all submitted a lot of good ideas, so it has taken me until now just to widdle the list down to 30 potential winners.
Sadly, there can only be 10.
