Enter at your peril!

This is the office door of one of my colleagues.  He is an entomologist (insect scientist)!  My office door is not nearly as interesting.  

Its intriguing how some people like to personalise their office space whilst others choose not to do that.  I know many people now work in open plan offices with hot desks so have little option but we are, in my opinion, fortunate to have offices for just one or two people.
