Floating Effect

Is there anybody who could help me make a movie clip or text look like it is floating? Is it done with motion tweening or actionscripting?\r\r\rAny help is greatly appreciated. Thanks in advance.

what exactly do you mean? can you explain a little more?

Sort of like a balloon tied to a chair…

A baloon tied to a chair ??? Any example on the net ??\r\rpom 0]

Im envisioning a balloon filled with helium, that has just been let go… it kinda hovers/bounces until it is just there and then… moves slightly in a particular direction…\r\rIs that what you meant?

i produced something like this using Math.sin() and Math.cos() it kind of gave the impression that the balloon was floating. I can probably make a file, but not until next week…
