The image above is a render of a clay pigeon. It’s not perfect, nor is it particularly good, but it only took about an hour to model in Blender, paint in PhotoShop, import into Unity 3D and begin launching them from a virtual trap house. This is the most fun I’ve had developing in a long time and I’m looking forward to (finally) getting into the App Store 
Integration with Flash & Flex?
Unity’s browser plugin can communicate with JavaScript similar to the ExternalInterface class in Flex, so there’s a possible integration point. Maybe that sounds absurd … doing the 3D game programming in Unity and building the 2D UI in Flex, but it’s possible. I’ll have to try this out; there are of all sorts of cool possibilities.
