While browsing the newly-updated iTunes store, I stumbled across the following podcast: 女の子の写真スライドショー/Japanese Cute Girl Slide Show. It’s exactly what it sounds like.
Of course, you could download the same photos at higher resolution from someplace like Zorpia, and you wouldn’t be limited to this person’s taste in music and girls. But then it wouldn’t auto-download a new one to your iPod every week, which I guess counts as a feature.
