Griffin Technology has announced the immediate availability of its Crayola ColorStudio HD accessory and app combo. Announced at the 2011 CES and recipient of an iLounge Best of Show award, ColorStudio HD was developed in collaboration with Crayola, and consists of an iPad-friendly, AA battery-powered digital stylus called the iMarker, and the Crayola ColorStudio HD app for the iPad. Together, they allow young artists to color and interact with special “live” animated coloring book pages, while automatically differentiating between input from the iMarker and the child’s finger; printing is available from within the app to AirPrint-enabled printers, and favorite works can also be shared via e-mail or Facebook. Griffin’s Crayola ColorStudio HD is available now for $30; the ColorStudio HD app is available for free from the App Store. For more information, see our full review.
