A superbloom is a natural phenomenon in which a large number of flowers bloom largely at the same time.
My pitch for this project is an interactive flower pot which allows you to grow (and destroy) a field of poppies by planting a paper craft flower into a pot connected to a MakeyMakey board.

When the program starts, the user can “plant” the flowers by placing it inside of a vase. The vase is actually a circuit, and placing the flower completes the circuit. From there, a signal is sent to Max to play a video file of a field of flowers growing. When the flower is removed, another video plays of the flowers wilting away/decaying.
I like the growing element of your flower concept and I wonder what kind of digital media you would like to use – video / animation / other forms?
