Remember that old tacky gift, the rotating tie rack? It would help men select a random tie, powered by an AA battery, and then sat unused in his closet because he didn't give a wet slap?
I have a closet with lots of clothing. I want to wear something different every day. Unfortunately, the layout of the closet encourages a set of "favorites" that get way more usage than another. This is because the edges behind the door are hard to reach. If I want to put the recently washed clothes there, I have to take everything out, put in the freshly washed, slide them to the end, and then put everything back.
So going with the "tie rack," and a thing I once saw at a dry cleaners, the closet is now a loop of chain, that gets pulled by a 5 watt motor when I press a button. I press this button when putting in freshly washed clothes, thereby moving them to the back. This way, I wear a variety of clothes -- the mad engineering way!
