How did you make the water? I feel the technique is the important part in this contest, but your SBS doesn't say anything about the water...

Really nice job author. The only problem I see here is that you've dropped the ring into water that has not fully settled. Did you use a k_speed daemon on your emmiter to slow the water down once the glass was full? I would have then set the water to an initial state and kept re-running it until the water was dead still. I know the water bounces around for ages once the object has been filled, but the mass rippling effect in the glass gives away the fact it wasn't still. I would typically run a 10,000 particle simulation 10-15 times at a 100 frames each time, to get the water to behave

fantastic ............
