Click the green flag and you can watch loads of graphs. They are marked with a rainbow line and the function is at the bottom. It's interesting (for people who like this sort of thing) but for some it's just either pretty or boring (or both together xD). So watch, spend the next half hour watching a line go across the screen. Press right and left to move to a graph while it is drawing, it will move to the next by itself if it reaches the end. Press 'S' to show/hide the function thing. The graph starts at a random number. Use arrow keys to change it. The graphs use very complicated functions to produce a strange wave - you couldn't draw it with pen. You can see the functions at the bottom - y = ?. The y is always based, somehow, on the x. Since the x is always changing as it moves across, so does the y, making a pattern. The functions use all kinds of operations from factorials to roots to random numbers, digits, trig functions, modulus, rounding, timer, mouse interaction and everything else you could think of.
