Einstein may have thought he had space and time covered with that General Relativity stuff, but we bet he hadn't bargained on this.
Designer Finn Magee has created an amazing series of two-dimensional, flat, images, which act as if they are three-dimensional.
'Flat Time' is a poster of a digital alarm clock, that actually functions as a clock, and 'Flat Sound' - a working speaker - and 'Flat Time' - an LED light - complete the full range.
Amaze your friends and preorder one now from here (the rest of the series is available from the same site).
