Clean One Pager promoting an upcoming survey taking app called ‘SQRL’. Nice touch with the newsletter signup form being shifted above the device on mobile to keep it above scroll.

This website has unfortunately redesigned or gone offline, so I have removed the link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this link on the Archive.org website. FYI: the site was first featured on 17 July 2015.
