Nothing I know of offhand but it can be done by using intersecting planes
having mirrored surfaces which form a multi-sided tube that the camera looks
through. Same as a real life kaleidoscope does. If there's a macro or other
script showing this it could probably be found in a search of the text or
binaries scene groups. Let me see if I can find one... No, not an example of
script anyway, although I should have a scene file I did long ago someplace
here.

You wouldn't need to see that, really. It's about as simple as:

intersection {
    plane {x,1 rotate 120*z} // sides
    plane {x,1 rotate 240*z}
    plane {x,1 rotate 360*z}
clipped_by {cylinder {0,7*z,2}} // remove excess tubing
texture {pigment {rgb 0} finish {reflection {1,1}}}
rotate 360*clock*z // make it animatable too?
}

// and something to kaleid
sphere {9*z,3 pigment {radial frequency 9} finish {ambient 1}}
