The Wörgl experiment shows how effective these alternative currencies can be: http://en.wikipedia.org/wiki/W%C3%B6rgl#The_W.C3.B6rgl_Exper...

Also, the United States went through a period of scrip currency during the Great Depression (though it wasn't quite a 'Miracle Experiment'). See the second image down for an example: http://americanhistory.si.edu/exhibitions/small_exhibition.c...

Does anyone have more information on Tems? I read about this yesterday on the Guardian (http://www.guardian.co.uk/world/2012/mar/16/greece-on-breadl...).

I'm wondering how inflation would play out in Tems.
