Low-bandwidth broadcast of spatially relevant information

Distribute short range broadcasting stations throughout the region that broadcast details of their site's history. Tourists walk around with radio receivers; as they go near a place, they can tune in to it. Different frequencies for different epochs.

You could build these yourself with a closed-loop tape, a cheap walkman, and a Mr. Microphone.

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.

Here in NZ we have something similar - a tourist information station, on the same (lowest in our FM range) frequency throughout the country. It gives out different information depending on where you are (over quite large areas though).

This idea is really #1, or at least tied for it: +

[jutta] showed up and posted this idea, then stuck around and continued to run the site for the intervening twenty years and odd.

Sometimes, reading it gives the impression that this idea has been baked.

Also, (belated) welcome to the halfbakery!
