[Alejandro Marin]"on creating different looks for the HVX 200."
Apparently Nokia is now making skins for the HVX to match their cell phone skins for changing the look of you cell phones. As well as the popular neon colors they have pokadot and other patterns to match your HVX to your cell phone to create a new look for every day of the week! Of particular interest to us cowpokes are the B&W dairy cow patch skins. :-)

Seriously, here are some links to Barry Greens DVD's and popular book. I'm sure there are other similar products that others can recommend. With knowledge garnered from these resources and a lot of trial and error there are many personal preferences you can achieve.
Depth of field attachments for 35mm lenses such as the Red Rock micro are probably the main add on you can use to radically alter the imaging you produce from the camera.
Matte boxes with creative/technical filters are other options as are Century w/a and tele adapters.
