For no good reason whatsoever, i’m playing with a ramp shader, using textures rather than colour swatches. Theres aload of cool stuff you can do with it - despite it all looking a bit like a crap photoshop plug in.

Slap the shader on a projection node oriented to the camera and flatten it all out! Its as if you pressed a couple of buttons in photoshop rather than took an hour over it in maya! Here it is on a face!
