The inspiration for this reveal comes from a series of pieces I did at an art museum six years ago; I had a bunch of paintings that I rearranged on the walls, occasionally while people were looking at the exhibit; like I did here, it wasn't immediately obvious what they represented, but on the last day a few lucky people got to see the final picture. While this isn't exactly the same, I think it successfully captures that feeling of a sudden reveal of something that's been a mystery for a long while well.
That piece is on my website in all its various incarnations, by the way. I suggest viewing them in the order listed.
