Looking down at groundfloor art gallery at Exeter College through a window one story above. The triangular shaper canvass that acts as a diffuser for a skylight is seen framing the painting one story down of the inverted triangles. Another interesting result in this composition is remeniscent of the so called Panavision Frazier Lens System except in 3-D. The Frazier Lens is designed to render movies of objects extremely close, perfectly in focus at the same time with objects far in the background. This is typically impossible or difficult at best.  This is hard to describe even with the explicit image above. Sometimes, images like this need to be shared in order to slap us into the awareness of how powerful a gift  stereoscopic perception  really is.
