Other Supplementary Material for this manuscript includes the following:
- Movie S1 (.mp4 format). The video shows thermal actuation cycles (25° to 75°C) of a pristine shell UV cross-linked at 35°C, recorded with a first-order waveplate, crossed polarizers, and one polarizer in the light path, respectively.
- Movie S2 (.mp4 format). Thermal actuation of a shell UV cross-linked at 35°C with a hole at the top, immersed in glycerol.
- Movie S3 (.mp4 format). The video shows actuation of a fragment cut from a shell UV cross-linked at 35°C.
- Movie S4 (.mp4 format). Thermal actuation of a shell UV cross-linked at 60°C.
- Movie S5 (.mp4 format). Complex modes of actuation observed by cutting a shell UV cross-linked at 35°C into different topological objects such as a cap shape, a self-closed ribbon, and a long spiral stripe shape.
