ok.

thanks matju for the comment, I got your point - it's very similar to what  thought.

About 4'33 I have I variation also;

0) Don't use a clock - try to measure the time with your time subective impression,

1 min) Close Puredata & all the software, shut down the system, turn off computer.

2 min ) Get out the room you are now

3 min) Walk

4 min ) Stop walking

33') Think about it.
