Sparklers would be a cool example of life for this project. Again, an awesome mood is set by it's own light. And everything els could be edited to be dimmer to draw out the rich color and light of the sparkler.
Oh, I LOVE how the photographer captured these colors! Almost looks like an oil painting from far away. Rain on the window pane, looking out of the hospital or a car. It doesnt matter the rain was one thing that calmed all the patients.
