This is one of the tests I made converting a level design from PS2 into PS3. Top one is the end boss fight from GoW2 that I made and the one below is the version I created using next gen shaders.
Everything you see here is made by me. The bird animation in the GoW2 scene is actually a pretty fun one. I used just a sinus curve type of texture that I scrolled across the mesh to make it run cheap.
