Plant Identification! ?!

Hello, for once i wasn't able to find by myself what this is.. (one time , looking for plant, that just out of nowhere was flowering, i even went trough 1000 plant pictures, to find out that mine was just clivia, wich i tough was just some green leaf-ed plant ) .
I bought it on sale, it was very small and poor looking, right now, in last 3 month it has grown by almost 20cm, like monster.

It's some kind of succulent, i think, but not sure what ...
can someone please give me a name for it ? :)

hope you can see- yfrog Photo : http://yfrog.com/ke84d0j Shared by blondecreature .
