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.

A335299 a(0) = 0; for n > 0, a(n) = abs(a(n-1) - n) if not already in the sequence, otherwise a(n) = a(n-1) + n.
