I'm working on a couple of new boards right now. It's a fantastic process, really. I love how everything falls on it's place, one thing by one, like details in Tetris game.
See this dialing rotary disk from old dial-up phone? A great find from my favorite junk-yard. The disk and base are all metallic, and mechanism works flawless. Stamp on it's back says "Made in U.S.A." It cost me barely 10 cents, and it's best centerpiece ever, imho, for a busyboard.
