A pen enabling the user to write and sketch in the air. By focusing a laser beam 100 times a second into a point in the space, the flowlight creates small plasma points that glow in mid-air. A series of points create a continuous glowing line that looks like a line. This product can be used in various applications from medicine to architecture.
The base focuses a laser beam 100 times per second to where the pen is, creating small plasma points that glow in midair.
Sounds vaguely like lightning, though presumably a lot safer. No need to worry just yet, though, since the Flowlight is just a concept — albeit one we would buy tickets to see in action.
