This is a cool idea. Rebilt is a gallery for redesigned projects. It allows you to see the evolution of a site or app design. Looks like they are also including packaging, logos and more.
Sure you can checkout the wayback machine to see older versions of a web design. But this is a cool way to visualize the full evolution.
Right now they are taking submissions and once they get their first 50 they will start posting designs on their site. I’m looking forward to seeing the first update!
