While looking for something else --Seems I DID get PhilC's $$ PHI Builder several years ago !!-- I came across Jim Burton's classic P3/P4 render test PZ3 from ~2002.
I've no idea where I got it, neither SCG nor R**y sites' 'search' recognise it, even a full-on Google found only mentions of folk mentioning it, without sources...
Any clues to current down-load location ??
