The top navigation mechanism is evidently a play off of the design of the magazine’s spine which is some sort of chemical-spectral visualization of one of the elements on the periodic table (for a full explanation of the design inspiration behind the magazine, colors and logo, read the foreword of the Feb ’09 issue – original magazine Creative Direction done by Stephan Sagmeister).
Either way, we’ve all seen this interaction paradigm done before, admittedly with more polish and smoothness elsewhere. However, as is with most content providers, content is king. And Seed’s content is some of the most engaging and rewarding out there for dorks like me. In this execution the interaction doesn’t at all get in the way of enjoying the content – in fact it enhances the overall experience by reinforcing the multi-threaded world we live in.
In all, go to this site not so much for a flashy new toy, but for the content – and along the way be engaged and rewarded. Kind of like the magazine itself.
(thnx Mulvey for pointing this out)
