Generating First Ideas

At the start, I was stuck for ideas. To start generating ideas, I went on wordle and put JFK's speech into it to produced a word cloud. This helped me think of words to start generating ideas. I then picked out words from this, and put them into a thesaurus to get even more word ideas.

This is what I got from my word cloud. The main words I got from it were the ones I put into the thesaurus.
The words I got were symbol, sanction, periphery, margin, spray, and graffiti. From these words I then thought of themes that could fit with this, and my main word was margin. From this, I went onto an idea about horizons, and sea/waves.
