Zen Brush

Today I got to take my mother-in-law to the eye doctor. While sitting in the waiting room, I started playing with a different drawing app than the one I normally use. This one is called Zen Brush and while it's not as full-featured as Sketchbook Pro, it does have some interesting pressure and brush effects. Here's my first zen doodle - everything except the signature was drawn with the same settings, so you can see the range of line thickness and darkness you can get from adjusting how hard you push with the stylus.
