I'm thinking of some ways to bring more immersion into the game.
One thought was to hook up misters on my monitor that spray when I'm surfaced. The only problem would be the keyboard!
Another would be a take off from some fighter flight chairs I have seen with sub woofers, but I would use an I/O controllers (PLC maybe) and some actuators to rock it back and forth with the wave action.
Of course having the red-blue-white lights for environment is a must.
Now with the surface conditions covered we need some underwater stimulus, any thoughts?
