Right this is a complex self multiplying / living swine wave computer science. this took me 2 .3 hrs to make getting y head around the formula. What it is doing is asking scratch what way so i do depending on whether you have viewed it more views equal more velocity. its weird and i learnt it at school, i have edited the swine so it is in a way living basically a living pen line so the line at the top is a dead line. its like a moniter device a moniter device is like a line that multiplys and devieds its self. THERE IS ONLY ONE PROBLEM when the line hits the wall or the edge it will not work sorry!
