One benefit to this is that even children can help with this type of wall (and probably would have full doing it). Also, sponge painting can be done on nearly any material, including cloth. And if painted on cloth like the pictured exampled, your "wall" can easily be rolled up and stored for later use.
While it's less three dimensional than some of the other methods mentioned here, it's simple and effective.

Stenciled Wall Painting
You can also use stencils and spray paint to help create your brick or stone wall. There are various places which sell stencils (you can see some I found on Amazon below), but since a stone pattern is not very difficult you might consider making your own.
You can use spray paint or sponge paint in several different shades of brown and/or grey to create the stone look. I found a tutorial here on how to paint a brick wall with stencils. You can also use plaster for an even more realistic look. Here's some info on how to do that. The instructions are for more permanent features, but possibly could be done on cardboard to get the same temporary look. Not sure how it would hold up...probably would need some extra support.
