Post-It Notes are not just office supplies; they’ve become pop cultural icons. From Sod using them in the Office to Post-it notes becoming a new decorating and art trend, the sticky paper seems to be taking over. Easy to use, easy to find (steal from work) and flexible, they are gaining in demand, despite the fact they have been around since 1968.

In fact, to mark their 40th anniversary, we’ve gathered a glorious collection of art and installation pieces made from Post-it notes. There really is so much fun to be had when your boss is not looking. Or you could decorate his cubicle as shown here.
