I saw possibly the same exhibit in a different city. They had a chunk of melting iceberg that was 27 degrees and invited people to touch it. There was the impression of many, many hands that had touched it. It was VERY cold. The passengers who went into the water that night were unconscious from hypothermia within 10 minutes and dead withing 20.
Several years ago, there was a Titanic: Adventure Out of Time computer game available. I bought the Mac version and played it. The most I remember of it were the various rooms and parts of the ship you could travel to. For its time, it was fairly decent. There was also a mystery game that took place at Versailles in 1685 during Louis XIV's reign. You got to go through the palace, and into the garden and maze that was once there. I enjoyed those historically-based computer games, but nobody really makes them anymore. The French company "Cryo Interactive Entertainment" that produced the Versailles game, and "CyberFlix" that produced the Titanic game went out of business a long time ago. I'd always hoped someone would make updated versions of them.
