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.
