I've always enjoyed jigsaw puzzles, but found myself annoyed when I couldn't complete one in a single sitting. Plus, if there were sections similar in color or texture, I'd kinda lose my damn mind. So naturally, I took on a 550-piece puzzle of edge-to-edge Lake Superior agates. All agates, all the time. This puzzle featured nothing but a photo of rocks piled up alongside one another, applied to cardboard, and cut into tiny pieces that looked like colorful toddler choking-hazards.
