The Stock version's dark grey background in DSL?

[Resetti's Replicas]

I've found myself disliking that "shiny" background in the DSL bot lab (the background around the robot itself), and wishing I could have the plain dark grey that was in the stock version.  Can anyone tell me what files to move around if I want to make this happen?  Thanks.

I'd be interested in this too for making splashes easier.
