iPads are great for kids -- intuitive, interactive, and engaging -- and Griffin continues to expand the possibilities, and the fun, with peripherals like the Crayola Light Marker. With a large crayon stylus that's easy to grip and easy to use, you pair with Griffin's free app and then paint and play to your heart's content with a variety of modes and tools.
It's meant to use in the dark and at a distance, almost like a pointer driven light show. The crayon sends light to your iPad camera, and the camera interprets that and makes it into magic. Check out their CES 2013, and if you have kids, or just like drawing in the dark, let me know what you think.
