This is a magnificent multi-function prop. When you press the white button on top, the light in the cup flashes. When you press the top red button, you can scroll thru a number of sound effects and sound clips. When you insert a data card in the card slot, the (4) lights on top blink in a random effect and trigger a sound effect. The buttons on the front panel act as "data input" and light when pushed. Finally, there's a "sample slot" on the right hand side; slide in a sample tray and it will turn on the blue scanner light and sound effect.
