Play it is.

So after hitting my head against the wall trying to find a suitable theme for the interactions and asking my myself a hundred times 'What exactly is the play I propose to achieve?', I began looking up the word 'play' itself.

play

(verb)

- To occupy oneself in amusement, sport, or other recreation

- Engage in activity for enjoyment and recreation rather than a serious or practical purpose

I was still unsure of what I wanted to do then. While still looking up images for 'play', somehow this image really hit me.

Somewhere I began to realize, that using Play as a theme actually made the most sense as it was broad with many meanings and connotations (giving me enough to find something suitable in context with the project). Its an antonym (not literally but in some sense) of the word mundane, that my project talks about i.e. doing away with the mundane interaction of a piece of light. And I would be literally be 'Playing with Light'.
