The idea is to use rapid motions in 6 directions as switches. Press the space key to start. The position of the ball measures the velocity v of your mouse (or other input device). If the ball is in a coloured hexagon, it will react by by turning black for 'blink' seconds, gliding to the centre, and doing something else, in this case playing a sound, while the hexagon blinks white. Adjust the sensitivity of the ball by shifting the slider. New in this version: - Glide to centre after hitting hexagon. - New, more intuitive sliders. - Cumulative adjustable memory of past velocities. - Sliders to filters 'low' and 'high' to filter out unintentional movements with low and high velocities v. Only intermediate velocities influence the position of the ball. The 'memory' slider changes the response of the ball by giving close to perfect accumulation of velocities for large values (in effect, measuring position rather than velocity), while small values give almost instantaneous velocities. The project does not respond very well in (my) browsers but you may get the idea by tweaking the sliders.
