@Override
public void draw(Batch batch) {
    age += Gdx.graphics.getDeltaTime();

    final float progress = age * INV_LIFETIME;
    final float currentSize = Interpolation.pow2In.apply(size, 0, progress);
    final float currentRotation = Interpolation.sine.apply(0, TOTAL_ROTATION, progress);

    final Matrix4 original = batch.getTransformMatrix().cpy();
    final Matrix4 rotated = batch.getTransformMatrix();

    final float disp =
            +0.5f * (size - currentSize) // the smaller, the more we need to "push" to center
                    + currentSize * 0.5f; // center the cell for rotation

    rotated.translate(pos.x + disp, pos.y + disp, 0);
    rotated.rotate(0, 0, 1, currentRotation);
    rotated.translate(currentSize * -0.5f, currentSize * -0.5f, 0); // revert centering for rotation

    batch.setTransformMatrix(rotated);
    Cell.draw(color, batch, 0, 0, currentSize);
    batch.setTransformMatrix(original);
