I created a number of CGI sequences for a documentary in the series "Mysteries of the Deep" produced by Iconfilms for Discovery Channel, showing the two ships of emperor Caligula recovered from the bottom of the lake Nemi (a little lake near Rome) during the 1930s.
The wrecks of the ships were destroyed by fire during WWII, after about a decade from their recover (and after 2000 years of perfect conservation).
