Shimmerfall--place votes here

The Shimmerfall is a fountain that displays designs in cascading water: in this case the letters J and V. The flow of water in drives a mechanism that switches each channel quickly on and off to create the effect: as the water flows down, it passes through many small components that each 'shimmer', allowing the effect to be easily seen with a clear liquid. With a coloured liquid, the 'shimmer' portion can be removed as the effect will be visible with just the liquid itself. This model is the coding cylinder (pieces are printed separately) however the pictures will show the complete model and since this is an entry in the moving parts contest please place your votes for the model here :)
