Drawball

Drawball is a large online virtual canvas for anyone and everyone to draw on as they please. Once you enter the space (by disagreeing with the tongue-in-cheek license agreement at the start), zoom in on on an area that looks suitable and start drawing away. Just don't be surprised if someone else draws over your stuff in a day, or even sooner! The Hall of Fame's got some really cool drawings- including this two-part Dragon. Best part is, by clicking on any of the drawings, you get to see the process of their creation, stroke-by-stroke. Wikipedia has an informative about Drawball. It's rather interesting to note that there have been several community efforts to create large-scale drawings- like the Korean Flag at the center of this Drawball:


Oh and the area available for any individual user to draw on is roughly the size of the 0 on the "zoom 0%" you see at the left of the Drawball. So you can imagine how many people it took to draw a huge flag like that!

At the time of this writing, there's a really cool drawing of Mario wearing a cape and riding Yoshi at the bottom of the Drawball. I say at this time because drawings tend to get vandalized pretty often on Drawball- which is pretty much inevitable since it allows any and all users to draw anywhere on the Drawball at all times. Which does lead to the sad destruction of many a fine drawing (which is why the Hall of Fame exists- to immortalize such work) but it also makes the Drawball a very dynamic space.
