Randomlynx: Virtual Deathtrap

The first military submarine to sink a ship in wartime was the CSS Hunley. Created in the American Civil War, I think the Hunley is the essence of steampunk, only in real-life. The darn thing killed two of its crews, including it's inventor, so it's no surprise it didn't trigger a wave of popularity for submarines. Surprisingly, I found a very cool online virtual simulation of the CSS Hunley at the Sun-Sentinel. The feeling it creates in running it really does capture how terrifying and awkward it must have been inside the original Hunley.
