Custom Shadow Box keeps clients in the loop with Basecamp

I've would like to thank you and the 37signals team for constantly trying to improve Basecamp without making it too complicated. Not only do I find Basecamp invaluable for working with clients in my web design/development business, but it's also been great for my small but growing side business, Custom Shadow Box. I thought you might like to see how a screenshot of Basecamp made its way into a set of illustrations I made for explaining how my process works.

Thanks Corrie!
