Here are four cups decorated with the digits of irrational numbers. The numbers used were: pi, e, square root of 2, and square root of 3. OpenSCAD code is included.

The cups have 7 faces, "pages", with the first digit on one page and 50 digits on each of the remaining 6 pages, 301 digits in all. The pages are read like a book, left to right and top to bottom. If the base of the cup is resting on a clockface, page turns are counterclockwise starting from the page with the single digit.
