I'm obsessed with robots, cogs, gears, circuitry... I snap up fabrics in these themes whenever I see them (if they're not TOO childish) and they go into my personal stash, for MY quilt, which I'll make sometime after I've made at least one for everybody else. lol
It's gone outside of quilting too - my cubicle at work is full of wind up robots and other misc. robot-themed things. I'm such a child. ;-)
