Looks like either a crassula or a graptopetalum. The shoots are flower stalks.

Yikes. I really should have done more research. I'm writing a blog entry right this moment about how our first attempt at succulents failed. We had some Little Jewels and a bunch of other tiny ones that died almost on impact. We had four Sunrise Plants and, thankfully, three of them made it through the first year. The Echeveria shaviana are struggling but they seem to be doing making do. This one, however, barely survived. I think it's some kind of Echeveria but I don't know for sure. This one looked so healthy when we brought it home but it is completely gone now and I have no idea what it's called.

Looks like a gasteria, perhaps Gasteria bicolor. Reddening of the foliage is typically a reaction to stress, even more sun than it has been used to. That soil looks a little heavy and wet for succulents......that could also be an issue.
