A cool website

I found a cool website for the golden ratio. It is located at: http://goldennumber.net/ I was able to use this a couple of times with my class. I used it to open up a discussion of Phi. The site contained some very interesting facts and great pictures of art and architecture. I encouraged students to look at it. I came back to the site a few days after introducing and found that the students were more engaged to look at different information. It is so nice to look at a picture to gether and enlarge it to easily share the important features.
