Logical processes in a computer can be influenced. I used to use a game program that ended with steams of different colors appearing on the screen. I can cause the computer to select one color until I chose it to display a different color and so on. The game programmers would have used some routine to chose colors at random. It is done by mental selection.
All events that take place in the physical realm are preceded by mental /non-physical selections. It appears different but really it is a giant matrix and we can, when we have the "right credentials" toggle the selections.
