In this hands-on tutorial I will walk you through the steps needed to turn YOU into an interactive virtual polygon. How awesome is that? To realise our creative end goal we will be using Processing and several of it's contributed libraries. Obviously I will not be covering all the aspects or possibilities of these libraries. Rather this tutorial focuses on the specific steps needed to reach our proposed creative goal: letting you interact with the geometry on your screen in realtime. I will share three fully commented code examples of increasing complexity that'll give you a flying start. Of course from there, many more opportunities for further exploration will arise.
