In another Wii U tech demo from E3 2011, players are told to use the stylus to draw different lengths of lines, shapes, and angles. You can compete against yourself or a second player. This was a really interesting use of the new controller, but it did a great job of showing off the sensitivity of the touch screen. While this demo did not show any sign of the screen actually being “pressure sensitive,” it did respond very well to input from the stylus (similar to the DS/DSi/3DS screens and contrary to the Wii uDraw Tablet).
