US teacher tracks his bike rides by GPS - and creates some stunning artwork (road.cc)

This artwork is not stunning.

I was hoping for emergent beauty rather than intentional doodles. This art is mildly charming but I do not believe the term "stunning" is applicable.

Nothing special, and nothing new. I think I saw more beautiful work.

As for for the pictures: I expected a human male reproduction organ...
