My magic sandblaster offers me choices -- a crystal clear glossy (predictable) reflective finish, or a muted matte look that suggests an air of mystery. This is a detail of a piece I just sandblasted. The second (matte finish) photo really doesn't capture the depth, where the line recedes into the nether regions, and then reappears as if beckoned by some unknown force. I know, my mind is on overdrive. But that's the point, methinks.
