The sutures in the human skull are not random, as you have drawn them.The details are quite variable, but they separate distinct bones that make up the skull, and so one could say they meander along distinct paths. Maybe you want to look at an anatomy book.

But maybe you don't intend the lines to be sutures, but indentations of veins or something. Your call.

I'll try to send a diagram that I pulled off the net.
