Neat book load animation as you scroll as well as interactive page previews in this Landing Page for the Master UI Design book by Denislav Jeliazkov.

This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. However we have preserved an HTML version here, as well as the full Retina screenshot below. Hope these still serve some good inspiration! FYI: the site was first featured on 21 December 2021.
