As @Cdrandin says, this would need to be done in 3D space. There are a number of technical challenges going on in the video: depth of field, selection indicator, info displays tied to current selection, etc. But the basic concept of rotating the objects in 3D space is relatively simple. Here is a bit of proof-of-concept code. It demonstrates how it could be done in Unity. I'd likely do a 'real' system a bit differently. To use:

• Create a new scene

• Add some game object to the scene (placement does not matter). You can use the built-in objects, or any object scaled to around 1 to 2 units in size in world space.

• Tag the game object with 'Menu'.

• Attach this script to an empty game object.

• Run. Left/Right error keys to cycle the menu.
