Our Ideas and Additional Information:
Taking a picture of someone's face is a mathematical projection from 3D into 2D. This type of projection is called 'Singular' and cannot be mathematically 'Inverted'. Since we create a 3D face from a 2D photograph we chose the name 'Singular Inversions'. Some kind of reference to this would be neat; perhaps the characters overlap and their colors are inverted where they overlap. Or perhaps some other 3D/2D interplay with lines would be neat.
