Hours to Sunset Mosaic Sundial

Artist Shaun Tan creates a large mosaic sundial at the University of Western Australia.  What Shaun artistically designed based on Professor Kovesi’s hour lines was carefully photographed, scanned and reproduced as a pixilated map that was turned into 337,600 glass chips (tessera) by artisan tiler Iain H. Middleton.
