Face/Vase Optical Illusion

I was fiddling around with making twisting shapes that print in one go. This "twister" spun so well I wondered if it would be possible to create the Face/Vase optical illusion. I happened to have silhouettes of my daughters already from a different project so I used 3D builder to quickly set the profile into my OpenSCAD created .stl. I am including the .stl with my daughter's profile and a blank square so you can try it with your own profiles.
