PI in the Sky at SXSW, Austin
1042, 14 Mar 2014Happy PI Day (14 MAR 2014)
The photo below was taken in Austin earlier this week. Precision skywriting, displaying the digits in the mathematical constant PI. They just kept going and going - several planes, each stopping only to fiull up with gas and smoke and then go back up and continue the enumeration of the digits in PI.
