I have not, but they do sound cool!

It was neat. First thought honestly was aliens. Then I remembered Starlink was a chain of small satellites, looked up the locations and sure enough one had just gone overhead.

Fun story about iridium, I once sailed to Bermuda with someone who worked on the project for Motorola. They chose the name iridium because initial plans were for 77 satellites in the constellation. But at least one launch failed and others might not have worked so really it should be called osmium or rhenium.
