Thank you!
Now that I look more carefully, I think the first image that Leslieray found, by 4susiesjoy, may actually be one of the parents of this hybrid, Graptopetalum filiferum... compare these two plants. The hybrid in the other two pictures above seems to have fewer, wider leaves (which would make sense given the parentage).
I'm going to have to look at more images to be sure... in the meantime,
@4susiesjoy , do you have any more information about the plant in your picture?
