For those of you who don't know quite well what it is, It's just like the mouse only in the shape of a real pen, which makes it much more accurate and convenient to work with. It has different pressure levels which make the whole thing realistic, as if you were pressing the pen harder on the canvas to achieve a harder line.
It's a wonderful tool for graphic designers, and I can't put it down. :)
Some of the works here were made with the tablet, and some others were not.
The last two were drawn with Illustrator.
