However, we’ve learned our lessons and done much better with “Cute Math”(http://ibokan.com/2009/about-cute-math/) and “Eye Test“ (http://ibokan.com/2009/testing-your-eyesight-handily/)
The graphics are created from our own tools that will be open to public in April. I hope you’ll check it out later.
Thanks a lot for your comments, which is really what I wanted for this post.
