Another experiment done in Houdini. I experimented with the "for each sop" because I just did a tutorial about it. It's basically a tool letting you create some kind of recursive procedure. In that case, it permitted each copy of the tentacles to have different animation, lenght and shader. All of this is calculated randomly and it allows you to have a global control over the whole thing. (It could also have been done with the "copy sop" in that case). In a future version, I wish to implement collisions and upgrade the shader.
