Today for a game related topic: Flowmaps. These can be used to fake flowing liquids inside of a quickly executing shader. We'll create a flowmap in Houdini using the SideFX Labs tools in this Tutorial and then move over to Blender to build an animated shader that advects a texture using the vectors from the map.
