We've seen a lot of awesome cake designs over the years, but this is the first time we've been genuinely envious over what a six-year-old was served at his birthday party. After all, who wouldn't want an R2-D2 birthday cake that actually projects holograms like the one Marc Freilich made for his son Alexander?

Besides layers and layers of chocolate cake, R2-D2's outer fondant layer also hides a pico projector that connects to an external laptop playing Princess Leia's famous message, with a birthday greeting for Alexander tacked onto the end. As birthday cakes go it's about as awesome as they can get, unless someone found a way to blast a Rice Krispies treat edible lightsaber out of its dome. [WedgeStrap via Hackaday]
