Following on from the brilliant popup office we found some time ago, here is a lovely (slightly more managable) book which uses paper technology to display popup numbers.
Designed by artist illustrator Marion Bataille it is availalbe to order online. Called "Numero" it builds on her previous success with an ABC book. Available to order from Amazon.
