Playing the piano used to require enough space for a large piano or at least an electronic keyboard; however, the makers of the Virtual Piano have reduced the instrument to a device small enough to fit in your pocket. The keys are projected onto any flat surface using infrared technology. With two octaves of keys (or 25 keys), the Virtual Piano makes a great portable keyboard. The speed of your finger movements affects the volume just as the intensity would with a real piano making this more than just a toy for techies.
