At first sight, our speed curve pendant might seem to consist of some arbitrary wire. But this is not true at all.

First of all, the wire is in a very special form, namely a shrinked variant of a mathematical space curve, a so-called torus knot. This is essentially just a closed wire bent several times around a donut… the knots appearing in this way may become quite complicated, but many of them look nice because of their symmetry and interesting structure.

Moreover, this pendant belongs to our *speed curves* series whose feature is the fact that the thickness of the wire is not the same everywhere; instead, it depends on the geometry of the piece! Where the wire is stronger bent, it is thicker… and this has been done via a mathematical computation of the curvature of the wire at every single point of the wire!

Your object will then be 3d-printed just for you and sent to you in really short time where ever you are in the world.

Our speed curve pendant is part of our series “speed curves”. Not all objects from this series are online yet, but here are those which are contained in this catalogue up to now:

#### Speed Curve pendant

At first sight, our speed curve pendant might seem to consist of some arbitrary wire. But this is not true at all. Almost every detail is defined by mathematical formulas.

#### Dancing torus knot

This object looks like a piece of art. But in fact, it is "just" a mathematical curve, called 7/3 torus knot. Imagine a donut, and then tie a cord around it in some interesting way.
