Distort Nodes

Could someone please tell me where are these nodes, specially the “At” node?

I found three of those on the Texture Nodes and a different version of them on the Composite Nodes.
But most important, I cound’t find a way to use them with a cycles texture, the Brick one, in order to achieve a result similar to this:

Thanks!

These are Blender Internal material’s Texture nodes. Wont work related to Cycles while wouldn’t give any error message.
Probably vector part of Translate can be substituted in Cycles using Converter RGB Separate/ RGB Combine and appropriate Math nodes in between.
