In this tutorial I go into something I had a play with recently, which is using mograph's modynamics along with Cinema 4d's in-built metaballs to get some nice liquidy looking stuff, as well as having it interact with other rigid bodies like text.
I split it into two parts for ease of rendering and making them slightly more digestible chunks. Let me know what you think here or at http://www.ispeakinpictures.com/ where there's more tutorials.
(oh and this tutorial's intro song is Sam Cooke - Twistin' the Night Away!)
