• The position of the Saturn ring in the middle of the micro-rod is unstable and it can slip back into the point hedgehog at the end of the rod
• (AVI format, KB)

• In the case of longer micro-rods, the Saturn ring is stable also in the mid-position and it has to be pushed from the middle of the micro-rod to its end, where it transforms into a point hedgehog
• (AVI format, KB)

• Grabbing of a hedgehog defect by the isotropic droplet, induced by the heating of the tweezers at high power
• (AVI format, KB)

• Transition from quadrupolar to dipolar defect configuration using high-power laser tweezers
• (AVI format, KB)

• Collinear attraction of two micro-rods with parallel topological dipoles
• (AVI format, KB)

• Side-by-side attraction of a pair of micro-rods with opposite topological dipoles
• (AVI format, KB)
