Experiment

By far one of my favourites of this kind, this experiment combines a very simple set of techniques in order to achieve a digital   Houdini   effect. Born in p5js, it uses simple line drawings to reveal a hidden message, that exists within the blank page from the very start of the rendering process.

Most of the people to whom I've showed this try to make a game out of it and paint the entire canvas in black. Can you?
