This is a Space Command Center I built for my two grandsons for their new space themed room. With a LOT of help from hubby and their other grandma. The lights across the top and above the keyboard flash red, the "countdown" timers work, and the hand-held video game (Asteroid Blaster) works for sound effects and playing. The rest of the buttons, switches, locks, knobs and cables work only with their imagination. Hope they love it!
