These cement tiles were designed by Lundy Wilder, who built a hurricane-proof house in Gulf Shores, Alabama. The house survived direct hits from major hurricanes, Ivan and Katrina.
Doesn't the pattern look like a stylized representation of radar images of the eye of a hurricane with spinning clouds? Maybe that was Lundy's intention? Either way, it is a classy pattern and these tiles would look just as great outside of hurricane alley.
