I have to say this craze is so addicting, cause you want to try to make others understand what you are drawing. Plus for me is improving my drawing skills. Cause you can either explain it simple with an easy fast drawing but you can also draw it as good as possible and get notice by cool drawings. When I like to do it from time to time I will put down some amazing images. Also the cool thing is that you can see how someone is drawing it. But have to say sometimes it takes so long for them to draw something you can understand and sometimes you get something you would not be able to guess and would put it up on Facebook. It's allot of fun and addicting so very advisable to get it!
