A huge divide where even though everything is very futuristic it is very grungy and almost apocolypse dystopian. Maybe even a dark cyber punk feel. of corse alot of blacklights and smoke. maybe some simple sloagans written around telling people big brother is watching or obey or something like that. graffiti on stuff to make it look more cyberpunk would be kool too. even crossing out of a slogan or two. strobes on the dance floor and all the light shows ect to where the dance floor area is almost a transformation to a really futuristic luxury disco. it would add more to the divide feeling of the raw cyberpunk look and the high class rich dance party.
