I love to doodle. I doodle when I'm on the phone, on-line, in meetings, at restaurants. Pretty much everywhere. I always tend to take pen and paper with me where ever I go, just on the chance I might get some quality doodle time in.
I also own doodle-specific books:
Do You Doodle?
Doodle While You Work
Pocket Doodles for Girls
Just to name a few.
In school, my notebook margins were covered with doodles: flowers, vines running up the page, faces, stick figures and geometric shapes: triangles, diamonds, cubes. I wasn't not paying attention, I took notes. Plenty of notes! But if I wasn't writing down what the teacher was saying, then I was doodling.
I stumbled across Vi Hart earlier this year and despite her doodles being all mathy she has introduced me to some new favorite doodles to doodle. Her videos are awesome and both the girls and myself are infinitely amused by her classroom doodles. And as an added benefit, I can now tell people, "I'm not doodling! I'm doing Math!"
