BitBanger Labs out of Brooklyn, NY has launched a Kickstarter project that is quite the game changer for photographers who enjoy light painting. With the new Pixelstick you can "add photoreal images, abstract designs, and animation to your long exposure photos and timelapses."
Pixelstick is an innovative new product being launched through crowd funding that if it reaches it's goal, which I'd be surprised if it doesn't, would ship out it's product in May 2014. I can already imagine all the cool images hitting the market at that time using the Pixelstick. It really takes light painting to a whole new level. In short the way it works is that you can upload any image or various images that you would like to light paint to an SD card and then into the Pixelstick. The "stick" then displays that image one line at a time through an array of 198 full-color RGB LEDs so that as you move it your image is painted into your photograph. The results are mind blowing.
Be sure to check out the video the guys at BitBanger have put together on their Kickstarter page and read more about the Pixelstick. I've already tossed my money behind it as a backer and can't wait to get my hands on my new Pixelstick when they come out.
