(Links are listed below - still working out a couple of issues - apologies!)  I recently received a request for an engineering/technical/blueprint inspired room - for a girl!  I thought it to be a really fun challenge, and here is the result.  It could easily be used for a boy, but I really love the fresh feel of the true blue colors and white and I think it's a really bright and happy space for a girl.
