This Mom Dad ambigram is a nice short asymmetric ambigram (also known as a symbiotogram) that is an engineered optical illusion at work.
Take a look to the left, and you will see that this typographical marvel says 'Mom' one way and says 'Dad' the other way.
Simply mouse over the design to see it rotate.
