Finally, a camera accessory that won't be doomed to rapid obsolescence: the Pez candy dispenser.
Federico Sartorio recommends some basic modifications to the candy dispenser that will let it slip into the hot shoe atop your camera that otherwise would be used for attaching a flash. Use it to grab the attention of children you're trying to photograph--as long as you have plenty of available light.
Be warned that trimming the dispenser's "feet" could reduce its resale value on eBay.
