Hon Non Bo
This composition was inspired by the Prismas Basalticos (Basaltic Prisms) in east-central Mexico, about 50 miles north of Mexico City. This formation was created millions of years ago by a lava flow - stresses inside the stone as it cooled caused it to crack into segments with five or six sides. As cooling continued to the base of the flow, the cracks extended downward, creating closely-packed columns between 30 and 50 metres (98 and 164 ft) high.
