It's not that tough to build: create a comp with the video screens. Work in square pixels for simplicity. Make this comp twice as wide as it is tall. Use this comp as a layer in the main comp, and apply CC Sphere to it.
Okay, it's not REAL 3D, but it looks darned convincing as long as you don't want a 3D camera moving around.
