"Gone are the days when visitors are happy looking at animals and matching them with the information on the sign boards"

Wha? I would think that would be more interesting than having everything spoonfed to you. I can see the benefits, but we're getting far too lazy these days. I sound like an old man, don't I? I'm 23 btw :P

a shoal of fish swim past and the child closest to the screen collapses in an epileptic fit due to the screen refreshing 800 times :)

They have been doing this for years in the aquarium trade to identify CITEs protected fish (In just the same way as Dogs and Cats.). All they are doing is using it to bring up some infomation from a database. So? I thought of doing that years ago.

Should have patented it then, and now you would be getting 1c every time a fish swam past one of these sensors!

Ahhh... you assume it would actually update 800 times ....

I'd bet on the app segfaulting, it would be more likely for the child to be introduced to the GENERAL PROTECTION fish. Heh.
