If you look at the distributive law

A x (B + C) = (A x B) + (A x C)

and see rectangles, what, then, is wrong with looking at

A + (B x C) = (A + B) x (A + C)

and asking for a corresponding image–may be not rectangles flashing area, may be one of those impossible visions (of climbing Penrose staircase)...
