This is a new product called the Flypen. Although its being marketed as a toy, it does some pretty interesting things. You can write 1 letter commands like "S" for schedule and then write the details and it will remember them for you. You can also draw a keyboard and drums. Clicking on the instruments makes the sounds play from the pen's built-in speaker. It seems at least as sophisticated as the i-Pen or Logitech's IO Pen which require's use of Anoto's special paper.
