USB Plasma Ball

Just the word plasma makes you think of going boldly where no-one has gone before. However, the beauty of this awesome USB Plasma Ball ($10.95) is that you don't have to wrestle Klingons in the outer regions of the Thark Quadrant to play with it; just plug this neat gizmo into your USB port, and streams of red and blue plasma light will flicker out from the core of the hand-blown glass sphere throwing mesmerising light trails across its surface. Touch the sphere with your fingers, and blue light will shoot out towards your fingertips.
