I posted this a while ago, but seeing as it is now available stateside it’s worth a second look.
If you had the right sort of metal ruler and circular magnets, you might be able to replicate this yourself, or you could just spend £15 and get this one (thereby supporting the designer who thought up the idea in the first place).
