We’ve posted lots in the past about NYC Metrocard art projects, but this one might just take the cake. This Metrocard bicycle is completely covered with hundreds of the cards, perhaps to make a statement about human powered vehicles vs. taking mass transit and the environmental impact you will have (not to mention the cash you will save) when you take your bike to work. In any case, it’s a cool thing to do with your expired cards.
