Figure 1.

Bundling dynamics on small and large scales. Top: a small-scale bundling process with three filaments and snapshots taken at times t = 0, 2, 4, 6, 8, and 10 s. Bottom: snapshots of the bundling process taken (from left to right and top down) at t = 5, 10, 20, and 40 s for semiflexible fibers with stiffness $\kappa =0.07$ pN⋅μm² are shown. Fibers in the same bundle are colored with the same color. The two networks at the middle are before the coalescence transition time ${\tau }_c\approx 16$ s, whereas the two networks at the bottom are after the coalescence time.
