This video shows the water surface refraction and real time global illumination in WOTA. It does not show any game play (but a weird rotating boat ;-) ). In the 2nd half the time of day is accelerated to show the effect of the global illumination: basically everything always automatically visually fits together - at any time of day or any weather. Unfortunately my touch solution isn't really smoothed yet which causes the camera movements sometimes to stutter, but the device can handle it at constant 60 frames per second.
