Another one that made me smile: doing the wave with your mobile phone. How does that one work? A Dutch company just launched SMSwave this week, at a baseball game of the Demon Astronauts in Amsterdam. First people in the audience register their participation by sending in their chair number via an SMS message - the 'wave' is then played out, by calling all registered phones in the right order, generating a wave of sound travelling the audience. Free to the audience, the service is open for sponsoring as well - users get a thank-you sms from the advertiser. Founder Jan Louwers has in the mean time patented the technology and is plotting away on making his sms wave global.
