What I can do:

Remove some of the coloured body to allow the background to be seen easily (this can be seen in the Chase's Place palette).

Custom fonts

Sticky nav-bar

Big chat-box

Transparent background (but images and stable sets are solid so you can see them properly)

Glowing borders.

Coloured background in forums (normally white)

Coloured training bars.

Coloured nav-bar backgrounds.

Links and nav-bar links light up on hover.

Change the colour of the input text box in forums.

Thanks for any help.
