The Gravity Dual of the Ising Model http://arxiv.org/abs/1111.1987 A quite interesting paper. Basically they define a way to sum over geometries in 3d pure gravity, they show the sum is finite in some special cases, and they find that for some choice of parameters out pops the 2d ising model, the simplest of all CFTs. Thus AdS/CFT is completely general (as many people, myself included, have long suspected/hoped). In the words of Hudson: "That's it man, game over man, game over!" I would like to understand their story better.
