Chankillo, Peru
The Thirteen Towers of Chankillo run from north to south along the ridge of a low hill within the site; they are relatively well-preserved and each has a pair of inset staircases leading to the summit.
The rectangular structures, between 75 and 125 square metres (807-1,345 sq ft) in size, are regularly spaced - forming a "toothed" horizon with narrow gaps at regular intervals.
About 230m (750ft) to the east and west are what scientists believe to be two observation points. From these vantages, the 300m- (1,000ft-) long spread of the towers along the horizon corresponds very closely to the rising and setting positions of the Sun over the year.

Tacita Dean
Tacita Dean, Installation Views, The Green Ray, 2001, color film, 16MM, silent, 2 1/2 minutes."In America they call it the green flash. When the sun sets, in a very clear horizon, with no land mass for many hundreds of miles, and no moisture or atmospheric pressure, you have a good chance of seeing it. The slowest ray is the blue ray, which comes across as green when the sun sets in perfect atmospheric conditions. It’s the last ray as the sun recedes with the curvature of the earth. Like a pulse on the horizon. It’s totally fractional, though it can last longer."

What is reality ?
I really enjoyed this programme, particularly the part about the Double Slit experiment, but it went over it a bit too quickly for me. It's talking about what I'm interested in right now. Basically how we create our reality simply by observing it ????
