you know, there are really two things in that illustration:  an image 
mapping with an armadillo painting and a displacement of the plane that 
vaguely resembles the contours of the armadillo figure, it got some 
weird bumps in the body that don't seem to match with anything in the 
figure.

anyway, I googled for an armadillo image, dessaturated it in the Gimp as 
well as applied some Gaussian defocussing in order to get a truly smooth 
displacement with a height_field:

union {
	height_field { png
		"Armadillo3.png"
		smooth
		pigment { rgb .4 }
		finish { specular 1 roughness .1 }
		scale y*.02
		translate -x/2
		rotate z*180
		scale 3
	}
	light_source { 4-8*z 1 }

	rotate -x*50
	translate z*4-y/2
}

light_source { -8*z .5 shadowless }

camera { angle 50 }
