Prefer waving your hands wildly about in the air to ordinary forms of communication? Think that semaphore is just so 1790’s? Then you’ll find use for the LighTalk LED text messager; this sabre-like device has a built in scanner capable of assimilating anything in a 4″ x 7″ area into its memory. Four spaces will hold anything that you’ve written or doodled and displays them in a strip of orange LEDs on the condition that you thrust the thing about in front of you like a demonically possessed air-traffic controller. Though not really the height of style, sophistication or subtlety it is probably best for send rude messages to prying neighbours. The LighTalk can now be yours for $39.99 from Think Geek.
