One of the cool products that was showcased at the recent Special Event convention was something called xylobands. I’d personally never heard of it before, but I guess it has been on the market for at least the past two years or so. They are LED wristbands or lanyards that can be controlled remotely by a light board. They may not be an awesome product for some events just due to the probable cost of the units themselves, but in a concert or other darkened area, like a lawn or maybe even spread strategically on floats in an open lagoon, the effects can be amazing.
See for yourself!
