The first thing you might notice about the Illum is the forward slanting angle of the camera body.  A traditional camera is centered around holding the camera up to the eye.  A perpendicular body makes perfect sense for that purpose, but shooting with the Illum is different.  Shooting Lightfield is a computational experience.  The viewfinder is replaced by the touchscreen, and for this reason a traditional perpendicular form factor just won't do.    As you hold the camera out from the body to view the screen, your grip changes and your vantage point changes.  From these observations, we developed a functional and dynamic posture right into the camera - one as versatile as the shifting postures of the user.
