Some places can be very strict when it comes to office decor. Some places aren't as bad. If you're lucky enough to have a little leeway, I suggest getting a plant or two for your desk/office. A study was done that shows they really help out:
They help to reduce stress
They help to increase productivity
They help to reduce sickness and absence rates
They make work spaces more attractive to job applicants
They clean the air
They help to reduce noise levels
They can boost creativity
Now the only thing you have to figure out is which one(s) you want!
