Really love this, just feels so different from the ubiquitously monotonous landing page designs that are out there.
Still, I'm not a fan of switching between scrolling behaviour. Scrolling can either manipulate the "camera"/view, as it traditionally does, or it can manipulate the elements (moving them up against a fixed background) but I believe you need to chose one behaviour and stick with it along your website/app.
Seems like this is pretty much what Shapeways has already been doing for years.
Awsome ! The whole things isn't just looking good, its also has a great concept !
Nice project, design looks awesome!
