Why handmade keys?

Jimmy DiResta from Discovery's "Dirty Money" explains how and why he mods the keys he uses from day to day, making them into artworks:

Maker Jimmy DiResta shares his modded keys at World Maker Faire NYC. His collection of handmade keys are a combination of his problem solving skills and creativity. They are a great example of making art from everyday items without sacrificing functionality. Jimmy is a designer and fabricator who can make just about anything, from just about anything. He's a woodworker, he sculpts in resin, he welds, and builds with plastics. His hammer and ax skull and crossbone belt buckle started as one of his wooden carvings before he cast it in metal. On a recent tour of his shop, I found the sewing machine he uses to add leather fronts to his pants next to the high-end wooden display he was building for a pop-up gallery.
