Inspired by Tongari Boushi no Atelier Chapter 85 cover:

Trigger: holding green screen

Helpful words: upper body, picture frame

Initially, I wanted to train the recursion LoRA but it got inevitably distorted inner layers when recursion goes deep. Therefore, I stepped back and came up with this green screen solution.

For shallow recursion you can use Nano Banana using prompt like "Crop and resize the second image and fit it into the green screen area in the first image to form a recursion." However, results get unstable when recursion goes deeper.
