I really like it, but the mouse movement is a bit annoying, just a bit slow and always in straight lines. Can Wink configure that? Still, it's a great way of doing tutorials, added it to the Wiki tutorials page
One tiny thing, it might not have looked clear in the tutorial that you need to drag the light on to the layers bar to make it go to that layer. The animation just has a moving cursor and doesn't show changing cursors or where you press and release mouse buttons.
