Some boundary and area results on the terdragon curve.
Read draft 9,
"Draft" here means believed correct as far as it goes but with more material to be added. The LaTeX source uses PGF for the pictures.

.tar.gz includes generator and development programs
which are all GPLv3
up. They're mostly Perl and a bit rough. The document has some
self-tests in Pari/GP and its
functions are extracted to a
devel/terdragon-defines.gp which is
highly specific to the document but might be of interest for experimenting.
See Math::PlanePath::TerdragonCurve for Perl code implementing curve coordinate calculations. The corresponding TerdragonCurve section of the PlanePath image gallery has some pictures.
