How to do this stuff is more of an application question. You can easily
manipulate views in this manner with OpenGL ES. Look at the ApiDemos
samples for an example (Transition3D.java).

First, I suggest you read the various architectural info on the  
android site
for some background info. Also read the SDK info to understand the key
concepts that are implemented in the platform code.

Then look at:

frameworks/base/libs/surfaceflinger/*
frameworks/base/opengl/*
frameworks/base/core/java/android/view/*  (WindowManager)
