Studio 360: Design Challenge

Design Challenge is a great project that Studio 360 organizes. Every year, they choose a new concept and challenge people to redesign it. One of my favorites is the Valentines Day Re-design challenge. Here is a brief explanation about the project:

Five years ago on the show we redesigned Christmas. The whole holiday. We hired the graphic designer Michael Beirut, of the firm Pentagram, to come up with a fresh, 21st century concept that could be used — and loved — universally. Since then we've done all kinds of redesigns of symbols and holidays … including the rainbow Gay Flag, Valentine's Day, and the Monopoly boardgame. Now we want to know what big thing you think we should redesign next.

Is there a symbol, business, product, or system that demands a serious re-think?
