In 1972, Wim Crouwel and his Total Design company created an identity system for the Municipality of Rotterdam. The Gemeente Rotterdam identity used a hexagon grid to visually represent the city in an abstracted way.
At the recent exhibition of the work of Wim Crouwel at the Design Museum, there are some more examples of the identity and its application. These images are mostly taken from the fantastic book TD63-73 about Total Design, by Unit Editions.
As the book TD63-73 puts it:
"Rendering the entire shape of the town (sic) with 'honeycomb" shapes was a way to future-proof the identity: it could easily be adapted and able to respond to respond to any further development of the town's borders and harbours."
