Name	Time of Submission

kyttyee	2008-04-24 06:41 UTC
maiZe	2008-04-25 03:06 UTC

 

Celestia is the big winner of this contest, but has generously declined the prize, so the $20 gift certificate will be going to kyttyee instead. Apologies to maiZe for not having a second prize. :( Maybe you’ll win next time! I have more puzzles planned…. :)

Here is a complete solution. (Lots o’ spoilers, so don’t take a peek if you want to do the puzzle on your own.)
