Ephemicropolis by Peter Root

Peter Root who had 40 hours on his hands took 100,000 staples and made the Ephemicropolis. His city of staples covered a floor area of 600x300cm. The stacks of staples were broken into varying sizes from full stacks about 12cm high down to single stapes. Then placed in various stacks. I could only imagine the patience you needed to take the time to stack them and take them apart and arrange them. If you want check out more of his work on his site.
