I uploaded cairo dock themes that replace a bottom or top&bottom panels of Ubuntu fitting the 'Human' theme.
This one fits the 'New Wave' theme.
This cairo dock goes with just a few (but nice) effects. Its not too fussy. Theres no transparency to the brackground but you can add it yourself.
This is only the bottom panel replacement. If you wish to have the top&bottom-features dock you have to install the Human Like T&B applying launchers and behaviour and after that this dust theme dock WITHOUT applying launchers and behaviour.
Look at my content, I made docks fitting:
* 'Dust Sand'
* 'New Wave'

Have fun with it!
