Seadragon could be described as Instant Messaging for dolphins and
humans. It does not translate whistles. It tries to recognize them, it
gives a name to unrecognized ones, and it is up to you to figure out
their meaning, if any. It allows you to emit whistles underwater and
to see the text names of whistles emitted by cetaceans in response to

Mac Users: This version does not work on the current versions of Apple
Mac OS. It will probably work when Apple releases a version of its
Java Runtime that is compliant with J2SE 5.0.

Absolute power corrupts absolutely, but model train sets do a pretty
good job as well
