The doorbell on my front door is currently inoperative. However, instead of repairing the bell, Popular Mechanics has given me (you, us) a great idea to see who's coming up my walkway. By installing wireless webcams into innocent-looking Jack O' Lanterns on my front porch, I can observe the trick or treaters from my computer (or television) without having to stare out the window. Obviously, there are other terrific uses security-wise -- especially if you have young hooligans who like to throw eggs at your house, which is completely undeserved. Just sayin'.
