Hmm, its an idea. Not sure if my artwork skills are good enough though. 

You can get photos printed on blinds now.

Yep, that might be a solution too KH1. 

I like the window background - but the idea of the roller blind is novel (though expensive?).

Most of all I like the train though! The low shots really give a sense of a proper railway.

Cheers Mikkel. 

The vertical blinds are electric and remote controlled, but getting a set printed would be interesting. I might even have a go myself, even if I messed it up a replacement set of plain blinds wouldn't be too much.
