When the clock strikes Nine! - Mathematics and Creativity

A clock that has only 9's in it.

Having 9s does not make it special.... You can design a clock having only 9 with 9/9 (=1), (9+9)/9(=2), (9+9+9)/9(=3) and so on...

What makes it really amazing is the fact that... it has only 3 9s in each digit representation...
