Blackboard and chalk, marker and whiteboard, even laser pointers, all outdated in the face of this little wonder. Looking like a laser pointer on steroids, the Flowlight is currently a design concept that lets you write in midair with streams of light.

It reminds of that photographic technique where you leave the shutter open for a few minutes and you take a flashlight or a light source and draw shapes in mid air. The Flowlight does not require any professional DSLR, as it provides instant visual results. However, it has one minor limitation, since it's a two-piece device. According to DVice, the pen will only create light streams in the air above the included unit, a cone-shaped base station. This base is needed to focus a laser beam 100 times per second to where the pen is, creating small plasma points that glow in midair. That plasma tells me we’re actually dealing with some sort of controlled lightning.

As you can see in the first picture, this device can also be used to create cool drawings. I’m not that certain about the range of the pen. Anyway, we’ll have to wait a little longer for this one, since it is just a concept.
