Griffin has just announced Crayola ColorStudio HD for the iPad. The Crayola ColorStudio HD is essentially a kit that transforms the iPad into a coloring book of sorts. For starters, the Crayola ColorStudio HD app lets kids have fun while being creative and coloring in artwork. But instead of using their fingers to draw and color, they can use Griffin’s iMarker, which is essentially a marker-shaped digital stylus . With the app and iMarker, Kids can draw with the functionality of a marker, pen, crayon, and even a paintbrush. As a matter of fact, the iMarker can unlock special pictures, animations, sound effects and special effects in the ColorStudio HD app. The app itself comes with over 30 animated coloring pages. And once their masterpiece is done, kids can show it off by emailing it or uploading it to Facebook. The app also has printing support to any Air-Print enabled printer. Crayola ColorStudio HD, which includes the iMarker, is available for $29.99, at Apple stores. Meanwhile, the Crayola ColorStudio HD app is available to free in the Appstore.
