It's a mix of stuff from San-X's official website. Here's the downloads section (http://www.san-x.co.jp/charapri/top.html). Everything is free. I mean, I think it's really nice stuff, and it's fast and there's a lot of it, and it's free yes. I'm surprised at this.

I can't help but love the food cat icons. I'm not supposed to love cats this much, but...it's just overwhelming. They're everywhere.
