DigiTools is a set of physical coloring tools for the iPad that includes 3-D glasses and three apps. It is an effort by Crayola to bring the crayon's waxlike simplicity to touch-screen coloring, and a second chance to gain some needed credibility in digital creativity, after the poorly regarded iMarker.
The business strategy behind DigiTools has become common - offer a free teaser app that will not work unless you visit a toy store and buy a physical product. In this case, it is a set of tools for $20, scheduled to be in stores in two weeks.
From an iPad's point of view, each of the eight tools has a unique fingerprint provided by a set of capacitive feet. That is how it knows the difference between the Airbrush, a Sticker Stamp or the forklike Digital 3-D Stylus, which lets you doodle in 3-D, providing you're wearing the special glasses included with the kit. As with any standard capacitive tablet stylus, a tiny electrical charge is transferred from your skin to the screen, so no batteries are required.
