Tulips and other spring bulbs can be grown at any time of the year when grown in glass jars providing they spent 8 to 10 weeks hibernating in your refrigerator. Start them sequentially to enjoy a long 'season'. They make great gifts!
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.
