If you arrived here by searching for frottage, you probably want to try again with "frottage paint" if you're after information about the painting technique or "frottage rub" if you're after the other. This site contains nothing about either of those.

Random sites hosted on frottage.org: Iosat Ltd. (who design and manufacture professional CCTV control and switching products), Beck's illustration site, rjp's photos, semi-dormant rublog, and other random things he's done.
