[PLUG] OT: OpenGL Screensavers

Gentlemen, please!  For a bunch of techie-type nerds (and I say this with all 
affection!), what the heck is wrong with you???!!!???  The **whole** point of 
computers is to look cool.   Any actual work they do is entirely secondary.   
That's why it so important to have windows in the side of your case, with 
groovy blue LEDs on your fans.

There once was a famous historian of science (Samuel Florman) who's chief 
thesis was that engineers don't build bridges because they want to get to the 
other side of the river;  They build bridges because they **have to**.   It's 
known as "the existential pleasures of engineering", and I'm afraid I am 
terminally ill with this disease.

I run ~AMD64 Gentoo Linux (bleeding edge) and I routinely find that 
I've "improved" my computer to the point it doesn't even work any more. (For 
some strange reason, this tends to tick-off my wife when she needs my 
computer to check her eMail... go figure).  Once I get to this state, it's 
time to spend a Saturday afternoon rebuilding it from scratch.  
Ah, "nerdvana"!

On a more serious note, you are exactly correct JP:  Screen savers are totally 
worthless on modern LCD screens.  Old monochrome CRT monitors burned in like 
crazy, and I understand that plasma HDTVs do it too.   But the chance of 
actually **needing** a screensaver is pretty nil these days.
