⨳ I like this one.
⨳ Variation #1, The Found 50: You find the basic shapes of the 50 United States around you. In the top row above we have Utah, Illinois and Massachusetts.
⨳ Variation #2, Grafifti: Same concept, but you limit yourself to finding the state outlines in painted-over graffiti. In the bottom row above we have a less perfect Massachusetts, and a pretty decent Pennsylvania and Arkansas.
⨳ No need to be too strict about it — but it’s got to be somewhat close. Requires the same loose but discerning eye as Rock Shaped Like Shoes.
⨳ I will finish this one day.
