Yep, several layered textures all using image_pattern as an opacity modifier for
glasslike layers. It's the same technique as masking say, a leaf shape, but
instead of just black and white I'm using the various levels of gray in a
grayscale image for the transmit values in the texture_map.

Using an ior of 1.5 here; stacking several layers of these with some granite
normals to break up the smoothness of the "glass" can provide some weird
patterns and interesting stacked refractions...
