that's a nice site, the on mouse over functions are pretty nicely made!! though i can't really resist the click, so i could not stay there for long
I've seen the site some time ago, and whilst I disliked not using "click" intensely the first time, I was happier using the site this time around. There are issues with the concept, such as form submittal, downloads etc, and with all graphical designs there will always be placement issues, where the mouse wonders too far or waits for too long and then one has to correct, possibly go back a step and try again. In this particular case it seemed better than most javascript / flash interfaces with pop up sub-menus, perhaps because I am already prepared for the paradigm.
