The trouble with Russ' circuit is that it blinks on occasionally. You want it to blink off.I'm posting a 555 circuit for you to try. Keep in mind that it will eat batteries fairly rapidly, because you have 2 LEDs running most of the time. A CMOS 555 will save a little power.You can change the OFF time by changing R1, and the ON time by changing R2.http://pageproducer.iglide.net/ron.harrison/blinking_eyes.html
