The California Science Center has some fantastic rotating exhibits and equally interesting permanent displays. This photo was taken at the Cleopatra's Palace themed exhibit of Alexandrian artifacts recovered from Goddio's underwater excavations. The curation was fantastic and gave the feel of being underwater.
It's a must-see in Los Angeles. The space shuttle Endeavor has such a rich history and the California Science Center gives you the full experience. Including how in the world they managed to get that gargantuan beast from LAX to downtown LA.
