If you have spent any time watching babies you have witnessed the building of this thread: the effort by every baby to build the hand-eye-brain feedback loop. Every one of us is programmed to work at this tirelessly for years from the time we are born. Nature compels us to work at it by making it fun. For some of us, surgeons and artists, for example, this work extends into adulthood.

The Hand-Eye-Brain feedback loop is my starting point for finding a universal human capability that we can harness in the effort to make software univerally accessible.
