Nick Wheeler is becoming a dangerous guy to leave your boxes by. It looks like whenever a box is around, nick DIYs it into a lighting modifier. This is what I like about Nick, he is never afraid to experiment, be it a mission impossible image or a floor lit lighting setup, Nicks investments in setups pays up big time. I heartedly recommend to check Nick's flickr stream for more inspiration.
This is also my message to you. Go out and try something new. I bet that four times out of five you, like me, will end up with just another glued box. But the fifth time is the one that makes all the difference. This is the time where you put what you have learned by ruining the other four boxes into use and build a really nice piece of studio equipment and saving money for more lenses.
