A couple of sites I like

http://www.grupow.com/circulo/
Portal representing all the advertising agencies in Mexico. Only 80 kb.
Cool navigation.

http://www.crumpler.com.au/home.php
A complete contrast to the above.
I love it, its quirky, a little distasteful but funny and suits the brand.

Sorry if any have been posted before, haven’t been around here long!
