I like Object dock a lot, their are a couple of things that I would like to see a Modder make for it though which I think could make for a really cool looking dock - and I don't know if what I'm thinking can be done can be done but thought I'd put this out there.
Firstly that a dock be created which is purely a mirror as its texture with the usual slight S pattern through it that seems to feature on all the docks.
Secondly that an invisible light source above the dock shine down against the mirror to give a coloured reflection off of the mirror and onto a lesser extent the icons sitting on the dock.
Thirdly that the light source could be made to be any colour or cycle through colours depending on options provided.
As I said I don't know if this is possible - but it would look so cool.
