For all those that think that glass should be transparent and not matte, I have the following Dock mod. It looks a bit more like the Leopard/Lion Dock. It does not however reflect, rather you look through it. To activate it, type the following two commands in a terminal: Code: defaults write com.apple.dock hide-mirror -bool yes killall Dock I have not seen this mod mentioned anywhere else. I found it by looking in the Dock binary. There are a lot more strings with meaningful names like "mirror-reflection-opacity", but I have not found any other string that seems to do anything. Have fun! Oh yeah, if you want to deactivate: Code: defaults write com.apple.dock hide-mirror -bool no killall Dock
