Unique icon for the communication app. First of all it's incredibly designed and crafted with pixel perfect accuracy following the iOS icon grid system. Second of all - icon doesn't only reflect "ninja element" but it also abstractly describes speed, accuracy and communication (scenario: shuriken is flying from one person to another like calls and messages) Anyhow, the design is unique and really recognizable.

I wanted people to feel pleasure every time they open the app.
