2V-P is a visual performance tool designed by Ali M. Demirel and engineered by Pascal H. Lesport, as the outcome of their artistic collaboration.

2V-P aims to manifest the idea of a minimalist visual concept and an interactive performance technique which Demirel has developed through his live show experience.
