Yeah. It seems that most things are actually quite trivial in POV - at least in
the original latin sense, literally meaning "having three ways" ;)

In this case, another one would be to use the pattern as a function image (see
3.5.11.16) without the "once" keyword ;) (didn't test it, but I guess it should
tile like any proper image would)


You know you've been raytracing too long when...
    ... you know every little trick the POV SDL has to offer ;)
