The scribble game is my favorite game from childhood and one of the greatest exercises for creativity I've ever seen. Its simple: someone makes a simple scribble, then you look at it until you see some sort of design or image. you then finish the illustration to match the image in your mind. There are only two rules.
1) when creating the scribble, keep it simple.
2) when turning the scribble into the drawing no cheating by covering any of the original scribble with fills!
one last suggestion...finish the drawing with a different color so we can see the original scribble and how you augmented it.
feel free to rotate the page as much as you need while figuring out what to make of it, but never erase or obscure part of the scribble... it has to be part of the final illustration.
So here's the first scribble. what do you see?
