Projector as light, how to ?

    Hi all,
    I would like to use my projector and a jitter matrix as a light (going to be a very slowly move of random values of 4 char matrix).
    My question is how can it "sounds" like projector, with a quadratic curve for instance, like the joined picture:
    Thx you for your responses
