## 2D Flow Around a Cylinder

5000 forward (red) and backward (blue) integrated streak lines of a time step in the 2D time-dependent flow around a cylinder. The streak lines are rendered such that they become less opaque the closer they get to their seeding position at τ = 0.

## 3D Flow Around a Confined Square Cylinder

## Beads Problem

The cores of swirling streak lines (red) detect the attractor (yellow) in the *Beads Problem* flow in contrast to the core lines of stream (green) and path lines (blue). The streak line core is a 4D surface shown in the right image together with its intersection at τ = -9, which is a line in space-time that matches the attractor of this flow.
