Hi!
Actually I think the first suggestion #64 was better for the chage-pattern.
What I thought of was more something of a combination of these two images:

After seeing #72, I would say that this nice pattern works better as a plain 2D. So the swirl would probably need other graphical elements..
The new colorscale was also very nice, but the old is just a little bit better.
