Cylon-o-lanternFrom Evil Mad Scientist via MAKE via SFSignal: How to make a Cylon-o-Lantern.

Want to make the ultimate Battlestar Galactica-themed pumpkin prop? This HOWTO goes the extra mile in including circuit diagrams you can use to build to the red LED string that simulates the Cylon’s signature back-and-forth eyescanner. Original BSG producer Glen A. Larson liked the effect so much he carried it over to a later production: Knight Rider. Yes, this technically means that KITT was a Cylon. It also means you can reuse the circuit to build a KITT-o-lantern, though how you carve a pumprkin to look like the hood of 1981 Pontiac Trans Am is beyond me.
