A The Font Clock is a 21st Century take on the British 24 hour clock design icon.

Twelve different fonts are printed within the mechanism of the clock providing a random, mixed display of graphic language within a single timepiece.  
“The essence of the idea is the twelve fonts, all chosen for their design strength and individuality and all of which are twentieth century apart from one, an English 18th Century script, in theory , at given points within the annual time cycle, all the fonts will run together for 5 minutes.” Sebastian Wrong
