Inkling by Wacom, digitally draw anywhere.
Words can not describe how awesome this thing is! Wacom created a little device called the Inkling, which once in your possession will create magic, or something pretty close to it. Clipping the Inkling to any surface you want to draw on, and while you draw your illustration gets instantly tranlated into vector graphics that can be opened in Illustrator or Photoshop. Shut up and take my money Wacom!
