This is pretty nifty. Say you’ve doodled something. You then have an urge to share your doodle with the world. Scan it with the LighTalk device. Then wave it left to right, like a pendulum. Using persistance of vision, your work of art will be displayed for all to see.
It can store up to 4 images, uses 2 AAA batteries out of which you’ll get 10 hours of enjoyment. Granted you’ll probably get tired of it after 15 minutes, but at 40$, it’s not bad.
