April 2014 is Mathematics Awareness Month. The organizing committee will be releasing a different activity related to the 30 smaller images on the poster to the left. It is a great way to spread the joy of mathematics. What will you do to participate in math awareness month?

One of my favorite images is the T-rex (row 5, column 5). I wondered to myself, what is this about? Upon a Google search, I found that it was an optical illusion. As you move, the dragon appears to be moving its head and watching you. Check out the video below to see it in action and see how it works. I cannot wait to see the activity they have planned for this one.
