About This Design
Ulam Spiral Round Clock
If you plot every integer in a spiral and darken the prime numbers, something weird happens. A pattern emerges. There's no known way to predict where prime numbers will occur, but the beautiful spiral patterns they create taunt mathematicians with the possibility that there IS a way. Ulam, the mathematician who discovered this effect, did so while doodling on a napkin during a boring conference talk!

Absolutely loved this and so did my son. It was of a very good quality and now has pride of place in his bedroom. Highly recommended due to the superior finish. Top quality print and design.

Nicely finished with a subtle hint of perfection. Ensures frequency to look at Our Lady Of Perpetual Help when checking the time. A nice to have ICON at home. Printing was nice and well finished

Great quality clock and very well made. Just what I was looking for to finish my hall off. Looked in loads of other websites and eventually found exactly what I was looking for at Zazzle. Designe and colour is perfect. I just love it. Bought the medium size and fits well for where I was placing it.
