there is an example that add a zooming effect to the viewport here : https://github.com/melonjs/melonJS/issues/399 but it then zoom literally everything.  As we were saying before the same can be done to a me.Container, as they both implement the currentTransform property : http://melonjs.github.io/melonJS/docs/me.Renderable.html#currentTransform it's basically a matrix object, so you you can get crazy as much as you want with it : http://melonjs.github.io/melonJS/docs/me.Matrix2d
