Nitpicky, but calling something R^3 outside of an academic context when '3D' suffices leaves me feeling oversold and underdelivered. This is 3-dimensional, and no further info is added with R^3 while only making it slightly less approachable.<p>R^3 contains R^2 and R, but I can't change the view to just 2D or 1D, so why call it R^3?
