I've never had anyone guess correctly as to what they are, but I really like mine. I don't use them in shows because lighting is never quite right for where I perform, but I often used them in the restaurant I worked in. Sometimes I would just play with them and walk around to get some attention, and at Christmas, I would 'pluck' lights off the little tree they had to get some fun attention. I had a bunch of tables applause once while I was doing it for some servers. I didn't realize they were all watching. -Which also reminds me that the angles from a distance are awesome.
Remember to pick up two though. One is near useless, unless you have a specific effect in mind, like Jason Latimers for example.
