Kind of useless, kind of cool — an inside-out notebook

I’m not convinced that this is a product that the world actually needs, but it’s neat: The RevolveR.

It combines an average, everyday-looking notebook with the concept behind the Jacob’s Ladder children’s toy*

One of the commenters over on Boing Boing points out that it could be a useful addition to a magician’s arsenal. I suspect that if you wanted to write a very post-modern novel, you could print it on a book like this.

*If you don’t know what a Jacob’s Ladder is, check out this video. Warning: it starts slow, but gets wildly surreal about the 2:10 mark.
