This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

A079355 a(1) = 1; a(n) = a(n-1)-3 if n is already in the sequence, a(n) = a(n-1)+4 otherwise.
