HockeyPuck this is exactly the essence of the idea that sparked my initial question. Besides the technical aspects, is it possible to have more of a connection with the system you are interfacing with? What are the implications of this? By using controls that have a finer resolution, tactile response, and break the mold of what we are used to, perhaps they would lead us to new discoveries within our applications that we might not have made otherwise. Discoveries that would occur because we are interfacing with our systems on a new level. Often painters will look at their works in the mirror or upside down to see the work from a new perspective. Perhaps finding ways to interact with technology other than keyboard / mouse can give us a new perspective as developers.
