Serendipity and "Why Man Creates"

Have you ever seen a film or read a book  that you really really liked, and can quote from years later, but you can't remember what it was?

I was that way in regards to a short film I saw way, way, back in junior high, that I loved.  It was a witty examination of creativity and society, and it frankly, shaped my development quite a bit.  But I forgot the name, and could never find it again.

But I remembered one piece of dialog from it:

"Do you think that radical ideas which are rejected by institutions eventually become institutions of themselves and reject other radical ideas?"  
"No." 
"Oh...for minute, I thought I had something there."

While doing a quick web search to get the correct phrasing for the above, I found the film again!

Or at least I found out WHAT it is: it's Why Man Creates, a short film by the brilliant graphic designer Saul Bass.  Unfortunately a copy of the film seems very difficult to find, but there IS five minutes of it here.  A quick search of youtube reveals other things done by Saul Bass, such the title sequence to "Its a Mad Mad Mad Mad World", and well, all of these other films.

It's neat to find out the identity of an old film I loved, and also find out about an under-appreciated genius.
