It's easy to scare kids, but when you're older it's hard to think of a Halloween gag that could actually give you chills. Well, it was. This pumpkin is making the scariest face imaginable this Halloween: one that displays daily updates from Wall Street. It's cheap enough and easy enough that you could still probably put one together in time for the big night.
Put together by the diabolical DIY wizards over at Evil Mad Scientist, it uses a smallish pumpkin and a cheap, 5 by 7, scrolling LED panel. The microcontroller and all of the wires are tucked behind it, though you could probably toss it inside if you used a larger pumpkin.
