So you are looking for something along the lines of a cheap DIY steadycam? I know it would be impossible to lay a track on a dancefloor and having people moving about (if that's what you are planning to do) and falling over it. I've seen them on various sites and a few of the other members of the forum have discussed them before, so I'm sure there is some info on them buried deep inside one of the other sections here on the forum.

Try the Hardware section to see if anything is in there, I'll have a look myself to see if I can find anything. Also do a search on Google for DIY steadycams, you'd be amazed at the gadgets people create in their garages. Something like a tripod head, part of the centre column to hold onto and counter weights added to the shortened legs?
