I don't have a picture, but at the moment on my desk, there is my laptop, a Joker mug full of pens and pencils, a New York Rangers hockey puck I got from a friend for graduating university, a small stuffed lion I called "Detroit" and my Detroit redwings mouse mat. On the second tier (the ledge what you pull out and there is usually a keyboard) I have a book called Molecular symmetry and group theory by Alan Vincent, my blackberry, scientific calculator and a booklet which is my final year thesis on Protein-protein interactions: The influence of mutations and phosphorylation on ternary complex factor Elk-1 recruitment by serum response factor, on the bottom shelf there are two leather cases of DVD's and text books on Chemistry, biochemistry and molecular biology as well as a limited edition Dilbert book my parents got me for christmas.
I realise that it would have been better if I just posted a picture, but I don't have a camera with me.
