This is a modern version of a traditional Japanese instrument called the kokiriko or bin zasara. It's often sold with the generic name of "Latin percussion instrument." Instead of rope and wood, I'm using paracord and floppy disks. The sound isn't quite the same, but it's still fun to play with and put to use a pile of floppies we had lying around the office. Check out the video for an example of how it looks and sounds in action.
