This may sound like a strange idea but it would probably be possible, I was just wondering how I would go about it. I was planning on having the image of a cybernetic heart which would change colour & beat faster, depending on how much work was being undertaken by the system, on my dektop. This was partly inspired by the KATE OS II default desktop screen. I didn't know if it would work but then I remembered that I'd seen a screen-shot of a guy who had the DOOM health bar on his screen that responded in a similar way. Sorry if my explanation is a little confusing but has anyboby got any ideas?
