Markr - that is really cool that there is another thread going on about this elsewhere, thank you very much! I laughed when I read the original post ha ha
I skimmed though what I could for now and see they have wrestled with it a bit and one poster mentioned light as a constant. Still no one has mentioned sound. To me that is brilliant, as it is really practical!
I will have to go back when I get a bit more time and read the thread again, im not used to the lay out on that board and might have missed something in there. Very cool!
