Carrara is a bunch of programs? I thought it was basically RayDream 6.0, or 7.0. What else got thrown into the pot?

I have the whole Murphy story written down somewhere in one of my journals, but off the top of my head, it goes something like this:

Somewhere in the 50's, or early 60's, there was an Air Force Colonel named Pruitt. He undertook a series of 'Deceleration Tests' for medical research. [I think it had something to do with bailing out of a jet at high speeds] It involved him riding a rocket-powered sled, on rails, that would decelerate sharply when it crossed a water bath. Major Robert Murphy was his engineering officer. [I think I'm getting the ranks right.] Now, this was in the days before digital read-outs. Pruitt, while decelerating from 500+mph to 0mph had to read a series of gauges in front of him, and then write down the figures when at full stop. On the last run of the series, Pruitt failed to notice in time that some technician had installed the gauges facing AWAY from him. When he told Murphy about it, Murphy just shook his head, laughed, and said: "If there's two ways to do something, and one of them will lead to disaster, somebody will choose disaster". A few weeks later, Pruitt was at a press conference, and it was there that he told the story. quoting Murphy in the now-famous version: "If anything can go wrong, it will." Within months, aerospace companies embraced the term and were touting their wares as being immune to Murphy's Law. Thus Murphy entered the language.
