Basic idea:

A planet system in the universe, waiting for audience to explore three planets.

 

Structure:

- give out voice to ask audience come closer to touch the planet

- if audience touch the planet, all lights on the surface of the planet will be on in different patterns

 

Planet surrounding:

- one LED keeps rotating at the top

- if light sensor detects the light, all lights on the surface of the planet will be on in different patterns
