After I had put down the trash cans, I went and grabbed a camera with a macro lense to get a picture of this beastie. I'm guessing it's Platycryptus undatus, the tan jumping spider.
It's about 11mm long, hairy and black with tan/orange markings. It also has plenty of eyes, including a couple of big ones - a common characteristic of jumping spiders (Salticidae). They're said to be friendly critters, and sometimes will explore people. Normally I'll put spiders like this outside, where they're more likely to find food than in the house, but it's getting cold outside, so I let her stay in. Perhaps she'll chow down on some stinkbugs for me.
