How can I style this awkward room?

[Wishfulmakeupping]

We have a second living room which is used as a ahem man-cave and playroom. So basically its a room with sky sports and a load of toys :)

At the freshly decorated in this colour m.crownpaints.co.uk/en/colours/colour-details?colourDetail=%7B72BFA0E3-34E3-4846-8CA2-26F853491832%7D
and wooden floor down.

I'm looking for inspiration for pictures/prints I could put up that would suit both the rooms uses so I was think fun bold framed prints but so far I've come up blank. The sofa is likely to be black or grey and probably plain blinds so the bolder the better for everything else cushions and styling etc

These could be pretty funky lighting for the room: www.amazon.co.uk/Modern-Banksy-Graffiti-Ceiling-Pendant/dp/B00BFVEN2Y/ref=sr_1_1?s=lighting&ie=UTF8&qid=1413972907&sr=1-1&keywords=MiniSun+banksy :)

Thank you they look very cool but lighting already sorted- Im going to look through banksy prints to see if anything would work always loved this one but probably not for a playroom ;) www.easyart.com/prints/banksy/banksy-park-street-3-416605#416605-40-30-1

For our play room I have vintage French school posters that I bought on etsy, also have a periodic table (that I must get around to hanging up), a colour wheel canvas and a punctuation chart on canvas. They're interesting to look at and not too childish.

What about maps? I think they work for both uses. We have a couple of these wrapping paper maps, in large Ikea frames.
