I took a few pictures around our house this week. I had just bought two new lenses, and was trying them out. From Raynox, the set includes a 1.5x telephoto and a .65x wide-angle lens. They were priced attractively, but as they were designed for camcorders the quality is not stunning. (Note that "focal length" in the EXIF information does not reflect any multiplier or divisor provided by an add-on lens)
I also have been playing with free software called "panotools", and used it to stitch a view of the backyard from 3 photos taken on a tripod.
