I love this effect. Was pretty amazing what you could do using techniques like dithering and colour cycling on hardware such as the SNES which was limited to a hardware colour-pallet of 256 colours (though a total of 32k possible colours)
G+: I love this effect
I cannot even begin to express just how awesome that is. Thanks for sharing!
No worries. Was having a discussion with a friend about good ways of doing water animations, and I remembered having seen this a few years back.
