The use of Wink to produce useful presentations

Recently I've had the chance of using Wink to make an easy short explanation about the passive voice: how a passive sentence is generated step by step in a very comprehensible way. It surprised me how easily the different frames are produced by using the various tools you are offered ( bubbles, arrows, and a lot of other shapes which you can fill with a comment or a brief explanation) It seems I've found a very useful programme to present my students different grammar issues in a graphic and simple way.
I strongly recommend it to all my colleagues, especially those teaching foreign languages like me. It's worth a try!
