I am constantly searching for interesting 1:64 scale cars and dioramas. My belief is your desk at work or home should be a reflection of your interests. Work doesn't have to be boring!
I understand many of you don't have a work environment that allows you the option to fully cover your desk like I have, but I'm sure you can find a small part to showcase some of your favorite model cars.
Although I've taken to the extreme with close to 175 loose cars on my desk, it really does make long difficult days a little easier having something I enjoy looking at while I'm busy.
