Nice simple code too to get the job done surely would make a good instructable as mmiscool stated because it is such a common thing that people want to learn.
mmiscool has been the dev working hard at this project go for it show em a little love back and post us a link so we can see it I thing this should be a staple type project a good example to share with all. Remember pictures are worth a thousand words and videos are basically 30 pictures per second. All part of displaying of a good project but now that I have my questions answered I can picture it working like you just explained.
Thanks again for sharing!
