midterm part 1

My goal is to create a unique matrix rain simulation. I have started by simulating the effect of the matrix rain using classes and random number and character creation inside of a loop the give the effect of letters falling down the screen. I still need to iron out the fading of the letters and make the “rain” more concrete but i have the basic form down. However I want to add a interaction to simulate the start of entering the matrix. it would look as if the letters have frozen and then a zoom in effect like warp drive from star wars would occur. I still do not know how to make this happen so if anyone had an idea as to how to do this it would be greatly appreciated.
