YALI : Screenschots
 
The client is written in JAVA and uses the SWT of Eclipse to implement a basic GUI. The GUI shows the status of all LCN controlled lights and allows to switch individual lights on and off by double klicking.
You can also use the command line client to switch lights or to check the state of a light. The command line can also be embedded into Apple Speakable Items, like in the move below.
