This Halloween or anytime of the year, give trick-or-treaters the evil eye as they approach your home with these cool new Ominous Blinking Eyes ($40). These creepy peepers easily install in your window with suction cups or out in the yard with the included lawn stakes. They use electroluminescent technology so they're clearly visible day or night and it eliminates the need to purchase replacement lighting. The yese can be set to blink slowly or locked in to give a fixed, ominous stare. (via Michael Kiely)
