niccccccce! the experiments on your site are really interesting too... wow ... Nice, but ... I'm on Mac ... When I execute the code, after a minute or so the cpu goes to 100% :| a number between 136 and 150 I solved using kr method of XLine: XLine.kr(1,1/10000,dur,doneAction:2) but I really don't kn.. ( I tried using 1/100 instead of 1/10000 but it didn't work ) Good work ... I can feel the rain on my skin ( :P ).
