Laser competition @ Cookie Paris 2017

The first laser competition ever in a demo party. A refreshing contest with vectorial aesthetic. Forget LCD displays, there is no "real" lights inside, think a demo with a beautiful but brutal lightning system : laser lights.

Like in the old days when computers were clock limited, lasers mirrors motors are « slow » and this is another reason why it’s difficult/interesting : to deal with a few hundred points per frame.

Constrain is high to produce high quality visuals, what you see is what your get through skills and imagination.
