Whomever finally slays that grade school giant, the No. 2 pencil, will surely be crowned king of the land. Well, Adobe just sharpened up its sword. Yes, that Adobe is unveiling the Project Mighty stylus and Napoleon ruler, promising a new way to draw on your tablet. The Mighty is a pressure sensitive pen that connects over to an iPad or iPhone over Bluetooth and lets you doodle and dawdle your way through the screen, even using your finger as the eraser. The Napoleon acts as a normal ruler would, but also gives you the freedom to draw straight lines anywhere on the tablet when it’s pressed against the screen. Now if we could just do something about the books and teachers’ dirty looks.
