# Joerg Arndt and Julia Handl

Two plane-filling curves on the triangular and the tri-hexagonal grid.
The colorization makes the self-similarity visible: one curve consists
of 13 small copies of itself, the other of 25. These two curves were
discovered by Joerg Arndt in 2013, amongst about one million new such
curves.
