Growl has no plans of going away as we covered back in February, and it's nice to see people still creating excellent notification styles.
Last Sunday, Daryl Ginn (@darylbro) published an update to his Growl notification theme called BangTidy. The new version 2.0 features a stunning 3D splash effect, while remaining simple, clear, and minimalist. Your notifications are going to pop out as smooth as ever. I haven't used Growl (the universal notification service for the OS X) for a while now, but with this new notification style, I will definitely consider using it again.
