I tried Depth Spinner on Wednesday May 17. It is an easy program that gives the opportunity to anyone to experience and learn about them mechanics of our eyes. Perhaps for those who have just gotten into the field of science, this web site is completely helpful to understand the basic concepts of science and put them in practice. There is a lack of explanation about some more concepts relating to the main topic. However, it does a good gob as an interactive site.
It is a really easy program to use. I did not need any assistance or outside support to use the material successfully. However, it is too simple. I think it needs some more animation, more icons or navigational features.
