I made it for the first prototype of my thesis project last semester. This is an interactive ceramic installation. 

I arranged the ceramic leaves like falling leaves on the wall. There is a IR distance sensor, so it detects the distance between viewers and the piece.  

There are three stages.

The first stage is no one in front of it or someone far from it. It is on the wall like a painting. In general, people don't care much of paintings around them. When people don't care of it for a few minutes, it will move very slowly in order, from top to bottom like falling leaves. 

The second stage, when people find that it's moving, they will get interest of it and come to the piece. Then, the leaves will swing faster. The viewers will realize it's interactive. 

The third stage, people will come closer to the piece, then the leaves will shake fast. 

Problems from the first version.

1. wrong choice of background material and color.

2. motors didn't move smoothly so it makes sound. 
3. difficult to disassemble
