New to Face-making, and I suck at math, so I'm begging for some help here.
I want certain elements of the face I'm making to fade in and out randomly, not synchronized with each other. I've used the example fade in and out in the "Kitchen Sink" examples:
And I've read a couple threads on the sin function, but I am not getting it at all. I don't find the function definitions on the Expressions page helpful at all. There is zero explanation of what sin or cos actually do. I guess they make assumptions about the average person's math skills (I'm well below average).
So, can anyone explain what the above expression is doing, and how I can randomize it?
