The best site i ever seen : http://www.whoswe.com
It is a complex site .. very i can say ..
It is make`t in : html , flash and php it rules ~!~
If you will have time look on that site ..
Of course they are using high technology 1024 x 768 Resolution; Stereophonic sound, etc from 100 points i am giving up 101 !

That is all
