Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Using Crafty
A simple game of pong:
Crafty.init(600, 300);
Crafty.background('rgb(127,127,127)');
//Paddles
Crafty.e("Paddle, 2D, DOM, Color, Multiway")
.color('rgb(255,0,0)')
.attr({ x: 20, y: 100, w: 10, h: 100 })
.multiway(200, { W: -90, S: 90 });
Crafty.e("Paddle, 2D, DOM, Color, Multiway")
.color('rgb(0,255,0)')
.attr({ x: 580, y: 100, w: 10, h: 100 })
.multiway(200, { UP_ARROW: -90, DOWN_ARROW: 90 });
//Ball
Crafty.e("2D, DOM, Color, Collision")
.color('rgb(0,0,255)')
.attr({ x: 300, y: 150, w: 10, h: 10,
dX: Crafty.math.randomInt(2, 5),
dY: Crafty.math.randomInt(2, 5) })
.bind('UpdateFrame', function () {
//hit floor or roof
if (this.y <= 0 || this.y >= 290)
this.dY *= -1;
// hit left or right boundary
if (this.x > 600) {
this.x = 300;
Crafty("LeftPoints").each(function () {
this.text(++this.points + " Points") });
}
if (this.x < 10) {
this.x = 300;
Crafty("RightPoints").each(function () {
this.text(++this.points + " Points") });
}
this.x += this.dX;
this.y += this.dY;
})
.onHit('Paddle', function () {
this.dX *= -1;
});
//Score boards
Crafty.e("LeftPoints, DOM, 2D, Text")
.attr({ x: 20, y: 20, w: 100, h: 20, points: 0 })
.text("0 Points");
Crafty.e("RightPoints, DOM, 2D, Text")
.attr({ x: 515, y: 20, w: 100, h: 20, points: 0 })
.text("0 Points");Left paddle is controlled by W & S, right paddle by UpArrow & DownArrow.

Quick build instructions
The easiest way to build crafty is to use gruntjs, which requires node and npm. If you have grunt, node, and npm already installed, then run npm install from Crafty's root directory. (This will pull down about 30MB of node packages.) From then on, just run grunt to build.
You can also use yarn instead of npm.
