This is an EXCELLENT webcam. I've used it with WebCam32 for security surveilence, stop motion (recorded a plant grow from seedling to flowering over a period of 30 days), and very good macro shots.
I've seen a 3 lens pack from some camera outfitter online that includes: Fisheye, macro (probably more like microscope because the included lens can get fine enough to see between the ridges on my fingerprint) and telephoto or wideangle (can't remember).
One thing I did for fun was I had it record a frame every 5 seconds, playback at 15 frames/sec, while I was playing some CounterStrike....hehehe...wow...except for my eye's...I didn't move an inch for like 40 minutes!
I only wish the USB interface was faster...at 640x480x24bit color, I only manage about 2 frames/sec, plus it will blur a bit if you're moving too fast. At 320x480x24 it's a nice 10 frames a second with little tearing....excellent color.
