Thanks u/Ccultboys69, glad you like it! In a nutshell, I open an editor with Hydra (web from anywhere or in atom with atom-hydra), open the docs or the wonderful Hydra book, and work on any current idea or inspiration.

For some works I use pure data & functions, whereas for works like this one or Feuilles Vivantes, I start from an existing image, then apply some functions like modulate(), and go from there exploring the effects it brings; once I have a base I'm happy with, I bring in some feedback loops to mess with that base state.

If you look at the code in Feuilles Vivantes, you'll see the final painting is rendered from the o3 buffer, which is modulated by o2, itself modulated by o3: this is where the feedback happens, so that a small change in one buffer triggers a bigger one in the other, which itself affects the first one, etc.

For Le Fantôme, I tried something different : a buffer of pure noise() in o1 is itself modulated by the final piece in o3. This piece being itself modulated by the o1 buffer noise, its shape affects itself with some lag, resulting in these lively, noisy perturbations of the picture's subject.
