How cool is this:

Controlling windows 95 from a remote machine
This shows how to set up a two node distributed system. One node runs windows95 Erlang, the other runs linux Erlang. There are two example programs. A program which allows the linux Erlang to manipulate the windows 95 registry and a bouncing ball that bounces back and forth between the windows and the linux machine – the latter example illustrates platform independent graphics, and various distributed programming techniques.

And the winner of the language to learn this year prize is… Erlang.

(Added later: JInterface – an erlang/java interface module. Groovy.)
