I quite like Adobe Aero, all things considered.
I don’t know how they intended the feature of being able to use the pre-set 3D forms as masks to be implemented, but I really like using it as a way to constrain an environment to what appears to the viewer as a 2D plane.
This idea of extending one image into faux walls, floors and ceilings was something I first attempted in a middle school architecture competition. I won.
