I'm not too sure about the memory part. I mean the article did state that it was "suppose" to help you remember things but it worked for me but I'm not too sure because I'm really known by my family and friends for my good memory but some people don't have such a good memory.
I think this a really cool idea. I mean I tried it and it worked! These university students are using their minds for something cool and effective. The don't remove parts dramatically so you can't read the word or letter, but just enough to make a cool and effective font that you can read.
I think it is wrong for people to do this because we are damaging our world. You may drop a piece of trash on the floor and leave it. Well pick it up! Because if you leave that there, we are one piece of trash closer to killing our earth. Soon there will be no earth because of us. As people it is our job to do what we can to help one another and that means helping our earth too. Who's with me?
