Some sort of Carpobrutus maybe, Linda - I was going to say 'extremely funky Cotyledon' but we both know that's balderdash.

Thanks for the suggestion Jeff. I wonder about the flowers, though, because I don't know of any carpobrotus species that have that form or colour. The habit on this is more clumping than creeping too.

It's not a Carpo, Linda - I can't think of the genus I'd like to think it is, but it begins with a D and has a yellow flower. That purple bit isn't a flower, is it? I thought it was new growth.

Jeff, it's a flower and it's very unusual looking! Is the genus Delosperma the one you're thinking of?

Here is a closer pic of the flower:
