Demo 1: "Dolphin"
-----------------

Controls:
W 			Move dolphin forward (into the screen)
S 			Move dolphin backward (out of the screen)
A			Move dolphin left
D			Move dolphin right
Mouse			Look around / aim
Left mouse button	Use 'echo-ray'
R			Reset
Esc			Quit

How to play:
This demo puts the player in the role of a Dolphin looking for some food. The player can maneuver the dolphin around an underwater world and attack fish with its echo-ray. Okay, fine, so the echo-ray looks like a laser, shoots like a laser, and cuts like a laser - but it's made of sonic power! Big difference.
Fish will appear randomly in the water. The easiest way to approach them is to aim the camera straight at them and hold W. Press the left mouse button to fire the echo-ray when you're close enough.
In the center of the world there is a whirlpool. The smart fish tend to go *around*. (If you want to see the coolest thing this physics engine can do, head straight in. Warning: Not for fans of the TV show "Flipper.")

Further notes:
Firstly, a warning: this demo has a tendency to be rather buggy. If thing start going wrong (you'll recognize it when you see it) just close the program and restart it.
This demo was made to show off the abilities of the physics engine to simulate soft bodies and cloth. The dolphin is clearly a soft body. You will see that the dolphin can bend, stretch, and break, unlike objects simulated with traditional physics engines. Furthermore, the seaweed at the bottom of the world is also simulated using the physics engine. Try bumping the dolphin into it for a look at some cloth physics.
