The LighTalk can be used to doodle cute little pictograms or messages, then you turn it around, scan in your doodling with the edge of the LighTalk pen, press a button while you wave the thing in the air, and a row of LED’s will draw your doodle in the air. Kinda like the SkyWriter of days gone by (I remember that!)
It will scan and store up to four images at a time. How tasteful those images are is totally up to you. Marked down to $39 at CompactImpact.
