          actually, not female. sorry to burst your bubble that a guy would say "ewwww gross!". But I don't think that looking that close at a *picture* would be that interesting. Looking that close at the *subject* of the picture would be only slightly less appealing. I'd rather be *in* the subject!

I'm not arguing that ultra close ups of femaleness don't lose their appeal after you hit the age of 12 ( they do ), but you're saying that you prefer the lights off all the time ?

                      I hope you can all help me! I need to write a data management system to manage 30 terabytes of data that is being generated nightly! Yes, there's quite a night life where I live, I guess! Here's[^] a link describing this project! (My professor wants it done by the end of the semister, BTW) But hey, I get to play with a cool 3000M pixel camera!!! :-D Marc My website Traceract

It was DEFINATELY not right, but there were a lot of issues, mostly post natal depression that just turned to hell, and to be honest, after 6 months without sex, I stopped doing anything constructive about it. I'm just glad we got through it, now. Christian Graus - Microsoft MVP - C++

                                      Sorry, it was meant to be light hearted. No looking, no touching, yet second child? My lame attempts at a joke just don't go over too well in text:sigh:

                                        ah, but what was omitted was...although it is one bit wide, you need a recording device with 'advanced' perpendicular recording technology[^] and a vertical bit density of 30Tb :laugh: Steve

Sounds something like right out of Star Trek. Cool concept. ------------------------------- DEBUGGING : Removing the needles from the haystack.
