This was my entry for Sputnikfest 2010. I had an R2D2 made of 4 6" peanut butter cakes with the ball pan on top. The legs were made of rice krispie treats and covered in fondant. The whole head was hand painted & there is an LED light installed into the cake that swivels. I used an edible marker for all the details and cut out fondant pieces (also hand painted). The small Yoda was made of fondant/gumpaste and was placed on a cupcake for the judges to taste.
