Question Is it possible to manipulate a camera projection matrix as in this example?

I am not sure where to post this, please let me know if this is not the best place.

I have developed an sketch in Processing, where I could manipulate the camera to fit a custom projection matrix, as you can see in the first half of this video:

Is it possible to achieve the same results in Unity?
On the second half of the video, my best attempt on arriving on the same results by decomposing a projection matrix and applying each parameter individually to an Unity Camera game object. But this method is far from ideal since it excludes skews and other sort of distortions.

Any advices?

The Camera has properties to manipulate its matrix. See docs.

 

Haha, sorry. I guess this is the best you can do meet your daily quota.
Thanks for your very useful generic answer.
