In a system with no motion, subsystems may think they are in motion because their solution is that they are in motion.  Atoms are the simplest examples.  These systems have thoughts that are interacting with each other.  For example, if a shape has been peeled off of memory and is heading to the brain, it is the thought of remembering something.  Its shape is what it is, both physically and psychologically.  I cover this in detail in “Flatland Turned on Out” by Eric Eliason.
