Paraluna combines kinetic sculpture, LEDs and music. Its main component is a disc 10m in diameter with 17,000 LEDs. A computer controls the LEDs while rotating, raising, lowering, and tilting the disc.

Some of the LED patterns incorporate the rotation of the disk, creating spirals and radial shapes. Others utilize a persistence-of-vision effect, making an image hover in space above the spinning LEDs. A smaller piece called Spokes demonstrates this:

Surrounding the disc are several high-quality speakers that play classical music at comfortable, yet immersive volume, creating a comfortable, peaceful place to be. Visual scenes are chosen to complement each musical piece. It would be kind of like this:
