[?] Plot 3D (red-blue) graphs?

Hello!
I would like to create an own constantly moving-waving 3D graph of sin. So it should include two really similar parts of the sin graph as a red one and a blue one. I have written this code:

Plot3D[{Cos[x] Sin[y], Cos[x + .5] Sin[y + .5]}, {x, -5, 5}, {y, -5, 5}, MeshShading -> {{Red, None, None, None}, {Red, None, None, None}}, Mesh -> 30]

And it gives this graph:

The left is red as it should be, but the right side of the graph should be blue. How can I programme it?
Furthermore, I would like to displace the black (gray) grid, is it possible?
Thank you for helping me.
Best regards,
Kristóf

Hi,
Do you mean something like

g1 = Plot3D[{Cos[x] Sin[y]}, {x, -5, 5}, {y, -5, 5}, 
   MeshShading -> {{Red, None, None, None}}, Mesh -> 30];
g2 = Plot3D[{Cos[x + 0.5] Sin[y + 0.5]}, {x, -5, 5}, {y, -5, 5}, 
   MeshShading -> {{Blue, None, None, None}}, Mesh -> 30];

I’m not it is “pretty”, but IMHO this may answer your post

Do you want to produce stereo anaglyphs? If so, then you might want to look at this Mathematica StackExchange post.

Yes, I do. This is what I originally want. Thank you very much, my friend!
