The website is very minimal, with typography the focus. The navigation is in a sidebar on the right and just simple, grey text. Until you mouse over the sidebar. When you do, all the links turn from grey to green. It’s a really effective technique and quite eye-catching. It’s simple, but elegant, and not something I’ve seen before.
Now all I need to do is work out how he did it and then steal the idea.

I gave it a go, and it’s very easy. Took me 15 minutes to find out how he did it and then code my own (very rough) example: Trick navigation example.
All you need to do is apply a hover pseudo-class to a div, and target each anchor within that div (see code in comment below). That way the anchor changes when you hover over the div, not the anchor. Use some CSS3 transitions to add a little easing and that’s it.
