Adobe Creative Jam Submission:
First I 'Dumbed' down the theme which was a quote from Bob Ross "You need dark in order to show the light.". I dumbed this down to Contrast. I started with a mindmap of what contrast means. It can mean a lot of things like; Good/Evil, Depression/Happiness, Black/White and a lot of other such comparissons.
In the image I made I tried to capture as many as possible and I hope that worked out!
