Since Linda and I got our Wii about a year ago, we've gotten into the habit of making Miis for anyone who plays. And actually, we make Miis for friends and family members who've never ever visited us. Some are good, some less so.
I've just added a whole bunch of our Mii pictures to my photos section. I took pictures of the TV with my digital camera, then used my mad MS Paint skillz to add in an actual photo of each person in the upper corner. These aren't all our Miis, only about two thirds of them - the best ones. Go over and check them out.
