Got something here (though it's not the original article I remember) on a German
web page for teachers:

http://www.lehrer-online.de/dyn/bin/435242-437415-1-programme_rel_raytracing.zip

The same page (http://www.lehrer-online.de/povray-relativistisch.php) claims
that there is also some Unix version downloadable from some university in
Australia, but that link seems dead.
