The Four Frames of Leap.loop

The-Four-Frames-of-Leap.loop

Peter and I started prototyping what multiple device support would look like in LeapJS with skeleton tracking and ended up at this wild callback with quadruply-nested for-loops:

Leap.loop ->
  for frame in arguments
    for hand in frame
      for finger in hand
        for joint in finger
          drawSphere joint.position


Somehow, it led to me writing this song, "The Four Frames of Leap.loop":

In the first frame of Leap.loop, controller gave to me:
  • a gesture swiping sideways.

In the second frame of Leap.loop, controller gave to me:
  • 2 hands waggling
  • and a gesture swiping sideways.

In the third frame of Leap.loop, controller gave to me:
  • 3 fingers pointing
  • 2 hands waggling
  • and a gesture swiping sideways.

In the fourth frame of Leap.loop, controller gave to me:
  • 4 joint positions
  • 3 fingers pointing
  • 2 hands waggling
  • and a gesture swiping sideways.


forever waggling my hands for Leap,
