I have recently started a weblog: www.brookbanham.com/sketches. Its purpose is to quickly show the net ideas and non confidential projects that I may be working on. Instead of putting all these sketches in the closet, never to be seen again, I decided to publish them on the net, so not to go to waist.
It should be updated weekly, or as stuff developes.
I really love this idea. Its a great way to monitor you progression and thought process. Also makes a fantastic resource for any IDer or student. I am really learning a lot from your loose but clean drawing style.
