Slu,

do you have any ideas about how to make that q-r code matter useful for the e-o community? Special q-r modified games i.e. like "q-r code paper chases". Using q-r codes instead of paper chases; after shooting the q-r code with ones cell phone someones camera gets an enigma where to find the next q-r code chaser... Could be combined with geo caching.
