This is a HackySack containing a small digital counter. It acts as a pedometer, counting up a running sequence of non- stop hacks. Other settings could calculate maximum height attained (from the period), give a score based on your ability to match a preselected rhythm, and record average hacks/minute. Maybe it could calculate calories burned.

This idea probably missed its window by about 15-20 years. My main concern is that it runs a little counter to the laid- back 'tude the game engenders, but I do know players who have competed for both height and duration.

Not a New Jersey city. Not the latest internet trojan. It's a footbag...I looked it up. [jurist, Oct 04 2004, last modified Oct 05 2004]

       [l3EA], the counter is fully inside the Sack and is removable, through a Velcro-closure slit, for reading and setting.

       I don't know how it would work, but perhaps some kind of touch-sensitive device inside the hacky sack that sends a signal to a remote machine displaying your hacks.   

       This would also be good for soccer keepy-uppies. Personally, I don't lose count (because I can only do about five), but I'm sure it would be popular.

       They have somthing like that for baseballs You can do this with a accelerometer and timer. The sudden change in acceleration would tell you how many kick you got (subtract one to account for your last drop). The timer could estimate your highest kick.

       //removable, through a Velcro-closure slit, for reading and setting//   

       Way too fiddly. Could the display not be recessed, so as to be visible at all times? Resetting or other commands could be entered as a defined pattern of taps (for instance, shave-and-a-haircut resets the counter).
