GB Glace have a few high tech posters in Swedens major cities that double as consumer surveys. On the posters you can vote for your favorite new ice-cream, just by touching them.

Once the 'button' is pressed the digit counts it, and it does really work but photos taken in bright sunlight don't quite do it justice.
GB Glace launch new ice-cream flavours nearly every year, and sometimes get in trouble for it. A few years back Nogger Black caused quite a stir, while this year a glittery pink star named "Girlie" is ticking some people off for 'forcing gender stereotypes on young girls', and it's also gotten the consumer watchdog on the warpath. It's as if 'controversial' ice-creams are a marketing tactic. ;)
