The PixelStick is a light-painting device.
It is a battery powered stick containing 200 coloured LED lights (rechargeable batteries supplied but may need to be charged).
It can be used to project light to create amazing patterns as well as photo-realistic versions of any image you like (special formatting of image is required) via an SD card.
You can read more information (and watch some videos) regarding the PixelStick at their website.
