The WavyWand is a different kind of a light saber. No, it won't get you 'Anakin' status but you can be prepared to here quite a number of "oohs" everytime you wave this wand.
Just wave the wavy wand to write messages in air, created by LEDs that project a image in the air. With a USB programming cable (optional accessory available for US $9.99) you can program your own messages, images and even animations to make custom messsages.
The projected images and messages can be as large as 48x100 pixels and up to 20 characters in length. Available for US $29.99 from here .
