Beware I'm sure there are still glitches, and there's lots of cleanup to do - but here is a link to the live demo of the Learn to Read Visually app!  No website or anything yet, and the app is far from done. You have to match about 7 things to move through each scene, and right now I have 4 activities live. Just about all tweening uses GSAP - as well as the drag and drop,  the animation stuff is Spine.
