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.

A097485 Write the positive integers on labels in numerical order, forming an infinite sequence L. Consider now the succession of single digits made by juxtaposing Fibonacci numbers: 1 1 2 3 5 8 1 3 2 1 3 4 5 5 ... (A031324). This sequence gives a derangement of L that produces the same succession of digits, subject to the constraint that the smallest unused label must be used that does not lead to a contradiction.
