Hubby and I almost had this one! A small tap light was used for the light and my husband built the stand and a special board (using two round pieces with space in between) that hung from a dowel to hold the light and the top cake. One week later, I finally found those tiny lights in the wedding aisle at Michaels. Argh!!!! Hubby held the top cake while I installed the light and it fit so tightly that he had to hold it too long, thus softening the fondant and leaving finger impressions all over it. Darn it all! Cake was for my son's 21st birthday. He has his Associates in Digital Media Design and is now working towards his Bachelors in Animation. He dreams of working at Pixar one day, thus the cake. I have tons of pictures of the process if anyone would like to see them. MMF and a medium cupcake pan (the kind that you bake in two pieces) was used for the top cake.
