Still working on it. This game chooses a colour (press 't' to toggle settings to change) and a line of 100 strands of the colour of various shades follow the mouse pointer. Press 'd' Press 'c' to clear. Press 't' to change settings Press 's' to hide settings Press 'space' to change the background (27 different colours)
For longer, more ribbon-like patterns, position the mouse farther away and for more spiky and irregular movements, keep the mouse nearer to the line. Press F11 and put it in full screen, for a very big screen. Some colours are nicer than others (I myself really don't like the yellow) so that is why you can change them.
