Some of the most notifiable logos re very minimalist and that is the reason why this one is successful as well. the use of positive and negative space also contribute to this logo idea. It also has a cuteness factor which may pull in a target crowd.
This Mohamed Shihab design is easy to like. I think it's successful because the designer did a good job of incorporating the suggested meaning of the word with the form of the logo. The simple, but dynamic, color combo is nice too.
