Here’s another freaky gadget to show your geeky side. The LighTalk version 2 shows the world what you wanna show to them. Just scan the text with the push of a button and the LighTalk II stores it in the memory. Switch it to the display mode and wave LightTalk II back and forth to see the stored text with the help of LEDs. This new version can store upto 8 scans and if set on Continous Display Mode, it can show all the scanned text one after the another. LighTalk II also features IR compatibility which can transmit the scanned text into another LighTalk II.
It is available at ThinkGeek for $40.
