Bluetooth Totem

Last week I was in Munich. In my way back to Barcelona I spent some hours in the bayern airport and found several Bluetooth enabled totems advertising CNN news. Basically you receive via bluetooth an animated gif and a link to CNN website.
From the mobile phone you just had to activate Bluetooth, set your visibility on and after a few seconds you were requested to accept an incoming message from the totem. Quite simple... I saw something similar in Granada's Alhambra were you could get a J2ME Midlet with a visiting guide of the place.
Although the gif is lightweight and simple, I find more appealing the J2ME application!
