Sync!Sync!Sync! icon

Sync!Sync!Sync! is a backup application of Mac OS X.
"Sync!Sync!Sync! helps you to make copies of your data by synchronizing two folders. It's very easy to set up, and once this is done, all you have to do is push a button. Of course, Sync!Sync!Sync! can also run automatically while you are away from home, or sleeping."

I drew Sync!x3 icon last year. This time, I redrew this icon to be 1024px and details (but the appearance of this hardly changes).
It will be adopted at the next update.

I felt rhythmically and pleasant the sound of "sync sync sync". Therefore, I designed it like a toy car whose shape is a "folder".
