Neatoramanaut Senor Mysterioso (featured previously) did something neat that you would never have thought of in a million years. He crocheted an entire gun store! The pistols in the display case, the ammo boxes, the weapons hanging on the walls -all made of yarn! This was his Bachelor of Fine Arts thesis project. See details in his Flickr set for the installation. Link
