Credit for the photo goes to Bill Pugsley, Executive Director of the Texas Supreme Court Historical Society - http://www.texascourthistory.org/. Showing the east facade of the Tom C. Clark* building, which houses the Supreme Court, Court of Criminal Appeals, Office of Court Administration, Board of Law Examiners, and the State Law Library, Bill captured the reflection of the north facade of the awesome 1888 Texas Capitol (see http://www.tspb.state.tx.us/spb/capitol/texcap.htm) in the polished granite of the (let's face it, way less impressive) 1959 courts building.
The story behind the photo relates to an artist's rendition of the same image, which we have used in our Annual Report for years, e.g., see p. 18 of the 2008 report at http://www.courts.state.tx.us/pubs/AR2008/AR08.pdf. Our original director, Raymond Judice, was reportedly very fond of this rendition, but it has been mildly controversial in that some disbelieved the reflection could appear in this way. Bill proved that it could, but note there is one thing he could not demonstrate, which is a reflection of the south facade of the Capitol (see the photo on the State Preservation Board site above) as in the artist's rendition, a physical impossibility.
