I've a Lumix DMC-TS4, which seems to have the same specs as the newer FT5. I take crap photos with it, but I suspect that someone patient enough to learn to use it properly and to take their time with setting up the shot could get quite good results. The Lumix is good for light-painting in that it has a manual shutter control (up to 30 seconds). The idea of light painting is simple; leave the shutter open for a long time and blast the subject with light. Play with it a bit and you'll figure out a lot. If I remember correctly (I often don't), the AW120 does not allow manual control of the shutter. You can still lightpaint on many such cameras using modes such as "fireworks" etc, which may be exposures of a few or four seconds, but there's not nearly as much control or ability to light up something big with your caving lights.
