new office

I have been given a new office at work. My manager has been moved into the administration office and i now have an office in the lab. This now means that-

- i have noone of authority around me
- i am the authority

Unfortunatley my office is rather large and as i only have a desk and a computer -it echoes when i talk.
I have ordered a filing cabinet but i think i need more. A cupboard would be good and maybe a plant and a picture but not sure what picture i should put up. hmm.
