You have to hand it to some folks who always want a little more than what a product was designed for.  Here is a fellow, Mark Irwin, who decided he wanted just a little more functionality from his Nano so he looked around, found some unused "old stuff", mad a few modifications and voila, he may well make a million dollars from his design.  I sure hope he did the proper legalize to protect his very slick idea.

So what did he do?  He took an old slide viewer, neatly carved a larger slot, embedded some speakers and ended up with a very cool viewing station for his iPod Nano for watching movies.
