Clock made from a whirling, strobing hard-drive

This Strobeshnik clock is made from an old hard drive: "The digits are etched in the original platter and they're strobed from behind with leds. The HDD motor is driven by a custom circuit without feedback, hence poor startup performance and awful noise. Rotational feedback is provided by an IR LED/phototransistor pair near the place where the head arm formerly was."

The result is a whirling, grinding, eye-catching, unreadable kinetic sculpture. Now that's a timepiece!
