And the fun thing is, you can use anything to build koans, not just pyramids. Numbers, words, etc, etc...
For example:
The following koan possesses the Buddha Nature: Red, To, Boxes, Abbreviated, Particularism.
The following koan does not posess the Buddha Nature: Red, Green, Abbreviated, Calendars.
The rule: (The length of each word must be a prime number.)
--
Sucrose Octanitrate.
Proof positive that with sufficient motivation, you can make anything explode.
