Transmission for Brurry
Here we go.. square-rounded a.k.a iPhone-alike version for the most popular and free torrent client for Mac, Transmission.
Info:
You need to replace original Transmission.icns which located at Contents > Resources folder inside the app (right click, choose Show Package Contents).
Otherwise, it will show the original icon at pause and quit state.
Bonus!
Netscape Navigator got brurrified too. Cheers!
