Online photo editing:pixellate yourself with fotoflexer

There are now a variety of sophisticated photo manipulation tools just available on the web.  The effects on offer make it very easy to let your imagination run riot.  One that came up on the ILT Champions mailing list,the free  fotoflexer.com even makes it easier for you to protect the innocent, so here's me looking slightly pixellated.  You can experiment with the advanced settings to pixellate just a portion of the image, you can also set the degree of pixellation.  This may well be useful to remove identifiable areas from photos, either individuals or settings.  But that is just the start, there are a host of other effects and adjustments.
