Love these stamp designs. Shame they are only concepts, beautiful work by http://maandesign.com/

I wonder if it's a deliberate design decision. By obfuscating the menu slightly the content has to work harder to guide the user though the site. Especially on a first visit when a user is exploring , this means they pay more attention to content and don't look to the nav as a safety net?

Then again I could be over thinking it!

Good point, well made!

This is really nice. Google ventures have a similar nav on the re-design http://www.gv.com/. Behaviour is slightly different. Is this going to be a thing now? I really like it, quite "app-y"

Any thoughts/opinions on the menu pattern? I've seen it in similar variations in a few places now. The content is essentially the navigation on a marketing site like this, so does obvious primary navigation take a back seat to content that supports a users journey?
