I always had love for colorful icons on my dock but after few years I thought about something minimal. Behold, The Text Style Object Dock Skin and Icon for the Object dock or Rocket dock with few tweaks. The pack contains icons with PSD file so you can add more as you like. Export them into PNG format and you are good to go.
Help for the installation is in the pack itself. So what are you waiting for, download the pack and make your desktop unique from your friends and show off to them,
