Mostly for educational use.

Now small computers, such as Raspberry Pi, are available on the market.
And we can run EPICS on it to interface with REAL world.
In principle it is possible to run CSS or edm on these computers, I  
think it is better to have
light weight enviroment on these computers. So I took "Processing",  
which I happend to know.
"Processing" is supported by many artists, who are not technology  
oriented people in general, it means "Processing" can be supported by  
the beginners in programming as well.
This is a thought in my mind when I started this trial.
