SpaceFlag

When the SpaceFlag is waved in front of your eyes a message magically appears in space. The pattern of light which the SpaceFlag paints appears to your brain as a solid image (in the same way that a televison works). Any message (up to 24 characters) can easily be programmed using the two pushbuttons. As featured in New Scientist.

Uses 4 x AA cells.
