Designed by Duncan Frazier and Steve McGuigan of Brookyln-based BitBanger Labs, the Pixelstick is a fancy new gadget for creating long-exposure light paintings. The device reads digital images created in Photoshop (or any other editor) and displays them one line at a time through an array of 198 full-color RGB LEDs. The images can be any height up to 198 pixels tall and many thousands of pixels wide creating huge possibilities for visual effects. You can see more example images created with the device here and learn more about it on Kickstarter.
