Taken from the tumblr page of the temple posted by PigalleInWonder here some numbers and explanations:
Complex mathematical calculations and sacred geometry lies at the heart of the Temple’s design, with the number three as a reoccurring motif. The Temple for 2013 is represented by a three sided triangle with a third eye. This eye represents the third year in a row that a triumvirate of artists - Gregg, Lightning and Syn - have collaborated to build large scale art pieces at Burning Man.

Read the astonishing MOOP report for the temple. BRAVO.
