I'd like to rotate a letter about the y axis.  However,
i want the axis of rotation, the y axis, to split the
letter in half, on the x and z axis.

I.e., I want to do this:

translate object <-(1/2)x width of object, 0, -(1/2)z width of object)
rotate about y axis
translate back

how can I do this?

Thanks.

Ew!
I'm assuming you're talking about POV-Ray... it should be simple,
provided you know the dimensions of the object...

object_name {
        [other declarational stuff]
        translate <-width/2, 0, -height/2>
        rotate y*90
        translate <width/2, 0, height/2>

The only tricky part, esp. for text, is determining its size. What
I might recommend for this (unless somebody else comes up with
something better) is to put the text on top of a xz plane that
has a pigment with an x gradient...

pigment {
    gradient x
    color_map {
        [0.0 0.1 color rgb <0, 0, 0>
                 color rgb <0, 0, 0>]
        [0.1 0.2 color rgb <1, 0, 0>
                 color rgb <1, 0, 0>]
        [0.2 0.3 color rgb <0, 1, 0>
                 color rgb <0, 1, 0>]
etc...
    }

Try it and let me know how it turns out.
