A few years ago, Oprah Winfrey congratulated on her show the winner of=20
the teacher of the year contest in US because he was able to teach=20
astronomy to blind students. Through touch and feel, students were able=20
to "picture" the global constellation of stars under very finely +=20
specially designed umbrellas for those teaching purpose. It's difficult=20
for me to explain how the whole thing was made but I assure you=20
astronomy can be taught to students.
Anyway, accessible image maps should degrade gracefully in text browsers =
or in any browser not rendering images.
