Thank you for the code. I was thinking, that this were some combined
pigment-functions, but I bet your solution is way easier to control.

that.

One optimisation could be to reduce your containing box. If I see it
correct, it is way to big in the y-direction, since 1+sin(x)/2 and
1+cos(y)/2
can each not be more than 1.5. Both can't be less than 0.5. So you can
reduce your container box to y*1 and y*4, perhaps even more, but I'm not
that familiar with a threshold of 1. That will save you some rendertime.
