This nifty pocket laser light show from ThinkGeek features an “endless display of pulsating, morphing laser beam patterns” when turned on. Video demonstration after the jump.

Turn the unit on to either auto or manual mode. Optionally flip up the easel and just set it on the table projecting on a wall. The unit will automatically cycle through a myriad of pulsating patterns and shapes. This leaves your hands free for maximum beverage handling. Or if you want control, select manual mode and you can control via two switches and two rotating dials the precise pattern and rhythm that the red lasers display
