Mona Lisa drawn with a single line as a solution of the "Travelling Salesman Problem" (TSP) through 100'000 cities/points.
Idea, algorithm and solution by Robert Bosch ( See http://www.tsp.gatech.edu/data/ml/monalisa.html and in french on my blog http://wp.me/p3JiL-r9 )
This sketch simply reads a pair of .tsp and .tour files and draws the TSP path.
Looking for ways to make it less "technical". Feel free to give it your Da Vinci touch...
