Flipbook - another online Flash doodle board

Flipbook is an online graffiti board service from Japan. I've previously introduced a few similar services, such as Tegaki and Teiki Blog. They all offer pretty much the same service: you use your mouse to doodle freely on a Flash-based drawing board. Afterwards, you can choose to submit your work or just doodle casually. All submitted works will appear in a list, and you can also view works submitted by others.
