I animated the letter ‘W’ because I liked that it was symmetrical. My goal was to make it look like the lower vertices were being pulled down by an invisible hand. I wish the animation could take longer but I think the effect still comes across. I initially had some trouble understanding how to program the letters but after looking at some particularly well documented code I was able to figure out how to create the basic animation I envisioned.  (special thanks to people with well organized + documented code!)

Here’s what it looks like:

Here’s my code:

Anitype.register('W', {

// Enter your name

//code adapted from Bryce Summers 'M' anitype submission

// Make your animation here
construct: function(two, points)
{

// Reference to instance
var anitype = this;

this.duration = 1000;

// Create a Two.Polygon
var polygon = anitype.makePolygon(points);
// Set an initial state
var x0 = polygon.vertices[0].x;
var y0 = polygon.vertices[0].y;

var x1 = polygon.vertices[1].x;
var y1 = polygon.vertices[1].y;

var x2 = polygon.vertices[2].x;
var y2 = polygon.vertices[2].y;

var x3 = polygon.vertices[3].x;
var y3 = polygon.vertices[3].y;

var x4 = polygon.vertices[4].x;
var y4 = polygon.vertices[4].y;

var v0 = polygon.vertices[0];
var v1 = polygon.vertices[1];
var v2 = polygon.vertices[2];
var v3 = polygon.vertices[3];
var v4 = polygon.vertices[4];

//set easing
