I have already experimented with coloured shards and light and I really like how the shadows come out. However my previous work was very stationary and less thought had gone into how I arranged the shards. 

So to improve on this, I built a machine that rotates a rig, therefore I could now add shards around in a circle and by placing a light source in the middle, have a ever changing display of shadows on the wall. This is exactly what I wanted as I wanted to introduce the dimension of time. 

Alongside adding movement, I used my knowledge of colour theory to control the atmosphere. As these colours were being projected to a whole wall, by changing from cold to warm colours I could influence the atmosphere of the whole room for a short while until the blues turned to reds.
