Great looking theme! I've just gotten my triple boot (OSX Mavericks, Ubuntu 13.10, Windows 8.1) hackintosh set up and used this theme for the bootloader. I wanted to share, I've done a couple of custom bootloader icons for Ubuntu and Windows. I also included a blank one so it's easier to add more logos later. I resized for 1920x1200 but these are the default size that came with the theme. Enjoy!
