Project #1 Idea

My idea was to create a sky-like scene indoors. I would fill a space with white balloons of various diameters fitted with micro-controllers that controlled an RGB LED located in the base or middle each balloon. The blue LED would glow brighter the closer it was to the ceiling.  The green LED would glow brighter the closer it was to other balloons. The red LED on the balloon would grow brighter the closer it was to the 'sun' balloon. The 'sun' balloon would be a larger balloon that you could move around the room. Some balloons would have helium and some would not so those that coalesced on the ground looked like grass and those that coalesced on the ceiling would look like clouds and you could make the sun rise and set by moving around the 'sun' balloon.
