This one is similar but different to the previous example.  I painted this one with different colors of acrylic paints, with no browning sauce at all.  First some watered-down iron oxide yellow to create an even tone on the tortilla, then various layers of increasingly dark colors to build up the forms.  Check out the demo called Human-Animal Hybrid for the complete palette.  The paints were pretty diluted with water, and the color soaked into the tortilla, creating some soft edges.

After toasting it, I dropped it on the floor, where it shattered. 

Um, I meant to do that.
