A 3D model I made of one of the submergable speed boat designs.  I joked that it looked like a banana, so I put the fruit sticker on it, in addition to the other sponsors we had procured.

(Click on an image in the gallery for full sized) My idea for the game was for a submergable speed boat that could go through underwater tunnels and on the surface of open water.  Open water would be fun because the game play could be very fast, but the adventure of other under-water locations would be even more interesting. The concept was set in the future in an indefinite time. I still think it would be a fun game.
