I didn't know it at the time, but it turns out two friends of mine were bidding against each other in that auction, one of them just slighting out bidding the other.
Both the winner and I felt bad about our other friend being shut out, so I created a second proof, appropriately titled Sunlight and offered it to him in exchange for him donating his highest pledged amount on Moonlight.
It's a mirror image of the original, and it has a seventh and lighter layer added, in order to make the "sunlit" elements appear much brighter.
