Disney-esque Simflame bulb flicker box
One of the things that I've always liked about Disney theme parks is the attention to detail, right down to the lighting. Themed lands like Adventureland and attractions like Big Thunder Mountain that pre-date electricity use incandescent lights with a circuit that simulates the flicker of oil lamps.
There's been plans on the Internet for flicker circuits, but none of them hold a candle to SimFlame, which looks exactly like the effect used in theme parks (see the videos on the site).
This would be perfect for lighting around an indoor or outdoor tiki bar. One of the units can drive as many light fixtures as you need, as long as all the bulbs use less than 100 watts total.
