I blogged on this subject a while ago. Here’s another example to add. The creator Josh Worth describes it as a tediously accurate scale model of the solar system. I love the simplicity and humour.
The planets are scrolled to horizontally or jumped to via a series of buttons at the top of the page. In addition, Worth includes writing out in the vast nothingness of space to give a better feel for exactly how much of it there actually is.
Thank you Josh.
