Poor Russ. I have no proof that Bob Van Dyke dosed him, but there was Jefferson Airplane music playing much of the afternoon; I heard “White Rabbit” at least 3 times. When we got to the demo of me carving the central part of the design below, Russ struggled with the photograph – his eye & mind were seeing “innie” when it should be “outie” & vice-versa.
Here’s the same panel flipped upside-down. Sometimes the shadows being above the design make things weird. Right now, I can’t see it “wrong” – but sometimes I can. Russ couldn’t see it right at the time. Often I tell people to close their eyes, then look again. That often fixes it, but the best thing to do is put the photograph right-side up. Or like Alice, just bite from the other side of the mushroom.
