Reflection

Cross-stitch is the OG of pixel art. 

As it relates to key comparison, there's something special about the deliberateness of cross-stitch that really appeals to me. When I send someone a crypto fingerprint, I am sending them an assertion of my identity. That usually happens with a few clicks of a button. With cross-stitch, the process of making and transferring my fingerprint is extended to hours or days of work. The physical, finished product is something that someone can physically hold, and even cherish. During the comparison process, a recipient is holding a product of great effort, a potent reminder to take as much care in comparing every stitch as the crafter did placing them. 

(I swear I didn't set out to make my final project a computation problem, but somehow it always happens...)
