Wait a minute

The second quality fo a good english classroom is the patience. Even if technologies are progressing and broadband is more and more higher, however you need sometimes to be patient to see certain websites in particular those which need to download plugins or particular softwares.
The last example I found on the net is the french professionnal directory Pages jaunes which launched recently 3D maps of Paris and Rennes.
Check the speed of the manipulations yourself it's a bit sad because it's really interesting and everybody can't see those applications because it need very high broadband, and because it affraid some of the people to install the program.
