The Paradox Toolkit is an addon to create 3D optical illusions of impossible geometry in Blender 2.8. The addon includes a library of impossible geometry figures, tools to align an ortographic camera with the optical illusions, and tools to manipulate your 3D objects around the impossible geometry scenes.
In the Addon Wiki you can find how to install the addon, the quickstart guide, and a description for the addon tools.
You can check the quickstart tutorial here.
