Last week I received the Wacom Inkling to play around with to see if we were going to purchase some for students to check out. The Inkling is a pen and a storage device that records the pen-strokes as you put them on the paper. If you want to see more you can go to the Wacom Site here.
The second image is my first sketch with it. The one above it is my pencil drawing. I will be testing it out over the next few weeks and posting different drawings with it. I am not used to drawing with a pen so right now it is a little rough around the edges. It is pretty nifty.
