2013, Day 359 - Architectural snowflake

When I was in Mexico visiting Xochicalco they had a nice little museum which I visited after the site itself.  The day was getting hot and it was nice to be inside as the sun reached its zenith.  Inside I found this ceiling and loved the geometric simplicity.
