Mark II Smart Bookmark

As someone who regularly highlights on Kindle, this caught my attention. It puts the highlighting in your hand. Anything to help idea collection has my vote. I love how the design allows you to use it in an analogue way as a bookmark too. It looks pretty well made, with a kind of Apple / Dieter Rams design language. It also encourages reading real books, somehow inverting what's great about a Kindle. Super cool.
