This is a first attempt to write assistive software in Scratch. The idea is to use rapid motions in 6 directions as switches. Click the ball in the middle to make it measure the velocity of your mouse (or other input device). If the velocity of is in the range corresponding to a hexagon, it will react by by turning white for blink seconds, and doing something else, in this case playing a sound. Adjust the sensitivity of the ball by sliding the velocity measure. It does not respond very well over the web but you might get the idea by tweaking the velocity measure.
