Something similar to this at some places...At a zoo here, you can buy 'zoo keys' that you plug into a gadget at different animals and get information...and a 'house of the future' called Xanadu in Orlando Florida hands out little recievers you hold to your ear, and each room has its own transmitter telling you about the features. |

It gives out different information depending on
where you are (over quite large areas though). |
