Kurt Caddy, YTI’s summer 2019 artist-in-residence, has literally left his mark at YTI. This piece, called “The Cornerstone,” is now the first piece that people see when entering the YTI offices. Kurt sees the piece emanating from the idea that Jesus is the “cornerstone” of the Christian faith. In the lower left corner, there is a stone that sticks out from the rest in gold. All of the rest of the stones in the wall, though of different colors and consistency, depend upon that cornerstone to remain strong.
