It's nothing but lasers.They get right up close to the scanning lasers and use them to create "time tunnel" effects.

And please don't keep the laser on continuously for more than 60 seconds or it will get burnt.

This green laser light is perfect for applications where the beam must be observed. Clearly visible in the dark to use for pointing out stars, signaling or optical demonstrations. The laser comes in a sturdy, padded metal case.A patient's discovery that an everyday laser pointer helps him walk may point the way toward an effective remedy for a common and frustrating symptom of Parkinson's disease.Then Clark chanced upon a laser pointer. "I looked at the laser spot, and my feet just seemed to go to it," he says.

Although several options in 3000mw laser pointer surgery exist, our Harvard experts most often use the PVP laser technique, also known as the GreenLight laser. This uses a high-energy laser to vaporize prostate tissue that is obstructing the flow of urine through the urethra.
