Every now and again my mind will do something completely different and new.  I woke up one day and it was like a slideshow was going on in my mind.  My mind had created seven objects.  They appeared as painted cast iron.  Very quickly the objects changed from one arrangement to another.  It was amazing.  It was like my mind was making up problems and then was spending all its efforts to solve them.  I just sat and watched it.  The subject matter changes but the way it happens is the same.  These are pretty much what it lookes like except my mind does it much neater then i do.  It just seems to be hooked on making and solving puzzles.
