Remember the days before the internet? No, we can't either, but take our word for it, time wasting was still rife for executives, with gadgets like the Atomix office toy by Francois Dallegret.
It was originally made in 1966 as a teaching tool for physics classes – 6,000 ball bearings fitting perfectly together like atoms to create complex structures and weird patterns when shaken or tilted.
It's back in slightly reformed style today via Areaware, an acrylic casing holding those steel balls. Price? That's £53.
