"Surface of titanium carbide crystal" by Dr. Lynn Boatner and Hu Longmire

This image was captured by Differential Interference Contrast by Dr. Lynn Boatner et al of the Oak Ridge National Laboratory in Oak Ridge, Tennessee, USA for the 2003 NSW competition, where it placed 15th. ...But of course I will hone in on it because it looks so much like a landscape!
