This USB gadget will certainly provide hours of fun and if nothing else, something cool to look at while you space out in the general direction of your computer. Never fails to amaze! The plasma light will create a unique environment on your desk or work station. It's small enough for home or work, yet big enough to bedazzle the sales droid in the next cubicle, who was out of your league… until you purchased the Plasma Ball that is!
