Exotic Dancer Lighting Effect The strip clubs here have showers on stage.. I wanted to inject laser light into the water stream to light up the water with dazzling colour changes and strobing.
Electronic Jewelery Stylish necklace with SMD LED's that light up with beautiful fading patterns. The Ultrasonic Downconvertor Wouldn't be interesting to hear ultrasonics like dogs? Could ultrasonic be downconverted into the audio range?
Sonic Fly Popper Gun Point and shoot..With just the right wavelength and amplitude of sound waves...could a fly explode? Might be more fun than a video game..
Electric Rat Trap Uses microwave oven transformer to zap rats. Really messy.
Instant Hard Drive Eraser Power coil pack thats mounted on a hard drive. Tampering instantly erases hard drive even without power.
Electronic Wallpaper and Paint All the walls of a home are completely covered with flat screen technology. Have a new paint colour everyday!
I'll find it funny if anybody here can tell me if these ideas have been done before.. :)
