Would Like to Make a Dancing Flower, Like the One in the 90's

I have always been interested in arts, crafts and electronics, like many people who saw the Guardians of the Galaxy, at the end of the movie they show a small dancing Groot plant. There have many who have just taken apart (a now hard to get) dancing sunflower and just built one on top. Well, I want to know how to make my own. How to put together all the parts that make the plant dance, but I dont know where to start. Any help is appreciated.
