    // CODE HERE
   
		// ZIM VR
		// http://zimjs.com/vr.html
		// Takes content and displays it in left and right channels with position shift to look 3D.
		// This example is to be viewed in a VR headset that uses a mobile phone.
		// Have a good read over the docs at http://zimjs.com/code/docs.html?item=vr
		// On the PC, the content can be swiped for testing
		// but the visual effect is obviously not the same.
		// You can turn on the VR adjuster to help you bring the images closer together
		// so that you can use the cross-eyed technique to get a 3D effect.

		// PROPORTION - not really part of VR - just using to set depths and scales to circles
		// we will have six circles indexed 0 - 5
		// the 0 circle is the big orange one and the 5 circle is the small dark grey one
		// 0 circle will animate to 20 depth which is positive coming out of the screen (which is at 0)
		// 5 circle will animate to 5 depth so much less out of the screen
		// we will also animate the scale up to 2.1 for the outer circle and 1.2 for the inner circle
		// the rest of the circles animate proportionally between these bounds for both depth and scale
		// Proportion lets us do this without thinking:
		// baseMin, baseMax, targetMin, targetMax, factor, targetRound
   	const depth = new Proportion(0, 5, 20, 5);
   	const size = new Proportion(0, 5, 2.1, 1.2);

    // Prepare content
		// put inside one container with everything as if there is no depth shifting
		// keep content regX at 0 - which is the default - so do not centerReg() for instance
   	const content = new Container(stageW/2, stageH); // although it is okay to go outside these bounds
	
		// outer radius and true means to make the circles individual Circle objects rather than one shape
		// makeCircles is just a little function ZIM added for promotional purposes 
		// the circles are also used to show broken images ;-)
   	const circles = frame.makeCircles(50, true) 
        .centerReg(content);

        .cache()
        .pos(null, stageH*.2)
        .dep(0); // screen depth

    // loop through the circles and give them depths
    // we can start them off in 3D already by giving them different starting depths
    // but we will start them at 0 and animate their depths

        // circle.dep((total-i)*3);
