Classic green-on-dark icons make for a feel like you're looking at an old-school terminal. Looks really sharp!
ghPoison includes tons of custom icons, a pretty comprehensive list (all apps with custom icons so far listed at the bottom of the description)
15 beautiful docks and 10 stunning wallpapers!
If you notice your favorite app doesn't have a custom icon yet, please leave feedback and let me know what it is so I can include it in the next update!
