We introduce a versatile method for finding prime numbers that display surprisingly intricate visual patterns— hypothetically, any desired pattern is possible, with only mild distortion. We use this method to locate several examples of large prime numbers that are, in and of themselves, self-referential works of art.

This is a description of the Scmutils system, an integrated library of procedures, embedded in the programming language Scheme, and intended to support teaching and research in mathematical physics and electrical engineering. Scmutils and Scheme are particularly effective in work where the almost-functional nature of Scheme is advantageous, such as classical mechanics, where many of the procedures are most easily formulated as quite abstract manipulations of functions.
