Draw a box on your hand's center:

import de.voidplus.leapmotion.*;

LeapMotion leap;

void setup(){

  size(600, 600, P3D);

  leap= new LeapMotion(this);

}

void draw(){

  background(255); //background redraw

  for(Hand hand: leap.getHands()){

    hand.draw();

    float angle= hand.getYaw(); //hand's angle

    PVector pos= hand.getPosition(); //hand's position

    translate(pos.x, pos.y, pos.z);

    rotateY(-radians(angle));

    fill(0, 100, 150);

    stroke(0);

    box(100);

  }

}

Fly to right, ground translate to left:

import de.voidplus.leapmotion.*;

LeapMotion leap;

void setup(){

  size(600, 600, P3D);

  leap= new LeapMotion(this);

}

float groundDir=0;

void draw(){

  background(255); //background redraw

  //draw ground's box

  for(int i=-10;i<=10;i++){

    for(int j=-10;j<=10;j++){

      pushMatrix(); //matrix

      translate(300, 400); //ground's original x&y

      rotateX(radians(70));

      rotateZ(radians(groundDir));

      translate(i*30, j*30);

      fill(0, 150, 100);

      box(30);

      popMatrix(); //matrix

    }

  }

  for(Hand hand: leap.getHands()){

    hand.draw();

    float angle= hand.getYaw(); //hand's angle

    PVector pos= hand.getPosition(); //hand's position

    translate(pos.x, pos.y, pos.z);

    rotateY(-radians(angle));

    fill(0, 100, 150);

    stroke(0);

    box(100);

    

    groundDir= -angle;

  }

}

plane's motion:

import de.voidplus.leapmotion.*;

LeapMotion leap;

void setup(){

  size(600, 600, P3D);

  leap= new LeapMotion(this);

}

float nowX=0, nowY=0, nowA=0;

void draw(){

  nowY+=cos(nowA); nowX+=sin(nowA);

  background(0, 150, 200, 100); //background redraw

  //draw ground's box

  for(int i=-10;i<=10;i++){

    for(int j=-10;j<=10;j++){

      pushMatrix(); //matrix

      translate(300, 500); //ground's original x&y

      rotateX(radians(70));

      rotateZ(radians(nowA));

      translate(i*200+nowX, j*200+nowY, -50);

      fill(0, 150, 100); box(200); //ground's color and box's size

      popMatrix(); //matrix

    }

  }

  for(Hand hand: leap.getHands()){

    hand.draw();

    float angle= hand.getYaw(); //hand's angle

    PVector pos= hand.getPosition(); //hand's position

    nowA+= radians(-angle/40);

    translate(pos.x, pos.y, pos.z);

    rotateY(-radians(angle));

    fill(181, 181, 181); stroke(0); box(100);

  }

}
