Use enumerations and a switch statement to create and track the different camera layouts. Then switch camera layouts with mouse inputs.

Draw buttons on the screen that switch layouts from the multi-screen view to a fullscreen of each camera, and then switch them back again. This uses simple GUI.Buttons to change the variable tracking camera layouts.

Create a functionality that will hide the cursor during normal gameplay and reveal it while controlling cameras.

Write a script to set your cameras rotating on their own. Control speed, maximum angles of rotation, and then randomize their position. Learn to tie transform.eulerAngles to a sin wave over time to achieve a smooth rotation effect.

Add image effects to your cameras to match the game view and simulate a small camera lens. We use light and focus vignetting, chromatic aberration, and monochromatic noise to achieve this. IMPORTANT NOTE: Image Effects are a Unity Pro feature and are not usable in the free version of Unity.

We'll take our switch statement and reduce many of its cases to a few lines of code in a 'for loop'. This leverages the use of arrays earlier in the project.

We'll give the player the ability to zoom a camera in and out when it occupies the full screen. We'll restrict the max and min zoom levels, and tie in a GUI.Label to simulate a camera focal length readout.

We finish up by adding a servo sound effect to play whenever the camera is zoomed. This ties in an audio source component to the Input.GetKeyDown function.
