How do I turn off artwork in iTunes Mini player 11.0.4?

I have been very vocal in mourning the loss of Cover Flow but now I've given iTunes 11 a second chance on my MacBook Pro.

The most irritating thing is the Mini Player is no longer 'mini'. How can I turn off artwork display when in mini mode? The whole point of this is to enable iTunes control whilst working, but having a big square displaying album artwork is just counter-productive.

I just want the option of a minimalist player when working.

Thanks,

Rich
