The G10's macro mode is fun to play with. You're not going to get results like you would with a Canon 100/2.8 macro lens, but on the G10 it's a good way to trick the camera into blurring the background a little. At least if you're close enough.
I used the self timer and set the camera on the counter to snap these pics. The G10 does (by far) its best work when left in ISO 80. So check it out, your batteries and cat food can look this good with the G10's macro mode.
