CTF Challenge 96 - Tilted Viewpoint

This is a bronze cross that Ginny picked up in Greece in the late 70s. It has been hanging in the stairway for the 25 years we have lived here, and we all pass it many times a day on the way up and down stairs. I hadn't looked at it carefully in years, but noticed that I could get the stair rail to be a reference to tilt to.
