Twist and Lock by Harry Thaler

The whole concept is really simple, and you can do infinite things with it. The crates used in the pictures are special ones but you could translate this into regular crates in some similar way and also get funky results.

'twist & lock' by harry thaler is a system that allows the user to lock special crates together
in order to create different combinations according to the desired needs. users can apply
the system in different ways, for instance, as a book or wine shelf.
