It's complete "un-technical" but i love the idea: K-swiss sells a shoe that signals different flirt messages. It's a unique code and K-swiss will publish a special flirt guide. Right now they collect peoples claims on their website. The shoe is made for men 16 to 24 years old cause this target groups is used to flirt using symbols instead of words.

And that's the background idea: a generation that communicates via sms (1 quarter of turnover of O2 is from sms) more than via "sweet words" will quickly adopt this "shoe language". The flirt shoe uses 5 stripes - so here is my sign: 4 down 1 up = "looking 4 some-1". Easy right?
