Inspired by a new feature available on Android Lollipop named AnimatedVectorDrawable I found in this blog post and the availability of the Twitter Emoji I tried to recreate the same using JavaFX.

The result can be seen in this short video.

The process is fairly simple:

I used the SVG to FXML converter who is part of e(fx)clipse to get JavaFX representation of the Emoji Replace the SVGPath -Shape making up the mouth from the FXML with a Group Replaced it with an Path -Shape in Java code like this Node load = FXMLLoader.load(getClass().getResource("Sample.fxml")); Group group = (Group) load.lookup("#mouth"); //$NON-NLS-1$ Path p = new Path(); p.getElements().addAll( absMoveTo(0, 0), relMoveTo(28.278072,9.8921077), curveToRel(-0.178,0.097714, -0.444,0.1037832, -0.635,0.017601), curveToRel(-0.039,-0.017601, -3.922,-1.7600656, -8.7,-1.7600656), curveToRel(-4.766,0, -8.662,1.7424649, -8.7,1.7600656), curveToRel(-0.191,0.086182, -0.457,0.078899, -0.635,-0.017601), curveToRel(-0.177,-0.097107, -0.217,-0.2573337, -0.094,-0.3811452), curveToRel(0.129,-0.1304876, 3.217,-3.1820771, 9.429,-3.1820771), curveToRel(6.212,0, 9.301,3.0515895, 9.429,3.1820771), curveToRel(0.123,0.1244184, 0.084,0.2840381, -0.094,0.3811452) ); p.setFill(Color.BLACK); group.getChildren().add(p); Implement a PathMorphAnimation Use the new animation type PathMorphAnimation a = new PathMorphAnimation(p.getElements(), Arrays.asList( absMoveTo(0, 0), relMoveTo(28.278072,10.021449), curveToRel(-0.178,-0.06422, -0.444,-0.068208, -0.635,-0.01157), curveToRel(-0.039,0.01157, -3.922,1.156747, -8.7,1.156747), curveToRel(-4.766,0, -8.662,-1.145179, -8.7,-1.156747), curveToRel(-0.191,-0.05664, -0.457,-0.051854, -0.635,0.01157), curveToRel(-0.177,0.06382, -0.217,0.169124, -0.094,0.250495), curveToRel(0.129,0.08576, 3.217,2.091319, 9.429,2.091319), curveToRel(6.212,0, 9.301,-2.00556, 9.429,-2.091319), curveToRel(0.123,-0.08177, 0.084,-0.186675, -0.094,-0.250495) ), Duration.millis(3000), p); a.setAutoReverse(true); a.setCycleCount(Animation.INDEFINITE);

The source of the PathMorphAnimation will be available soon in the e(fx)clipse repo.
