Rich, that looks like some sort of begonia family to me. It sure looks happy!
Shane, check the floral department at supermarkets. Around here they are full of these cacti for the holidays. I have a big one that's decades old and a smaller one in a hanging pot that I started from a piece that broke off the mother plant. I've determined that these plants tend to prefer shade. In brighter sunnier locations the pads go from deep green to very faded, and can even develop a purple or redish tint depending on the variety. They like food, and unlike your classic desert cactus, want fairly regular water. I think a nice shady area on a porch/patio or in a Florida garden would be paradise for one of these.
We want pix if you get one!
