Tarpaper, Painted Wood, and Security Cameras
Syn means "sight" in old Norse. Odin, one of the principal gods in Norse Mythology had two ravens, Huginn and Muninn (Thought and Memory). I thought with all of the CCTV cameras that we have around, that if Odin was around today he would have a third raven named sight. The pedestal that the raven sits on is a replica of a piece of the Rainbow Bridge in Baltimore.
