So I've learned of a pretty neat way to push out or explore really crazy forms and shapes in a fun way.  Basically you start off with a quick scribble without looking at the paper and trying to see a form inside of it.  This is a pretty awesome way to explore new forms for whatever you're designing whether it be an actual product or a cartoon or spaceship.  Basically just turn the form into something.  I've included an already posted picture but it was the same process except I used a figure drawing and saw a face in the form.  I've included the scribble and then 2 other forms that came out of different scribbles.

It seems difficult at first but it's a good way to free your mind.  It breaks you from the repetitious style you would normally create.
