After seeing the number of ancient architecture with columns I decided to make the shots more interesting by combining columns with "Where's Waldo" (except it's "Where's Alex"). I can still remember my art history teacher singing to the rhythm and pattern of columns, but they were mostly indoor ones in European cathedrals. Don't have a lot of those.
Columns at Chichen Itza, Quintana Roo, Mexico
Columns at Arkadi Monastery, Crete, Greece.
Square columns near the Great Pyramids, Cairo, Egypt.
