Fireworks Accident

I'm not much for joke names (like M.T. Warehouse) or effects (such as glow-in-the-dark hoppers at a nuclear facility), but I thought this one might be fun. Since the layout's design precludes creating a traditional outdoor fireworks show, how about an indoor show in the form of the occasional minor accident at the fireworks factory?

Using a combination of two types of flasher circuits, 40 LEDs are flashed on with varying rates and effects. White LEDs are strobed using circuits from trade show buttons, while various colored LEDs flash in the same manner as the fireflies. Above left is the bundle of electronics; the LEDs are all clustered together in one large area inside the wing of the building, above right.

To enhance the effect, I added a sound effects generator. Custom-mixed from various sources, the sound effect is attenuated so as not to overwhelm the senses. The dark circuit board above left is the MP3 player; above right is the speaker.
