We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

If the mesh wasn't rotating about the proper centerpoint, I would expect it to overlap on one side and have a gap on the other. However, this shrinkage or growth is uniform all the way around the inner mesh. Additionally, the above image was taken after 5 full rotations, so the mesh should've returned to it's initial rotation.
