Leaving Job/Crush in 2 Days - How to Tell Him I Like Him Before I Go?

I temped at this job for a few months. My assignment ends in 2 days. I really like this guy at work. I'll never see him again. There is no fraternizing at this company; no one talks. It's all work. One of those big companies that's laying people off, everyone walks around on edge - there's no socializing opportunity whatsoever. People don't say more than hello. He seems to be doing all the body language things and giving out every non-verbal cue that he is interested. But there is just no way if he WERE interested, for him to let me know. How do I let him know before I go? Do I? I feel that there is mutual potential, but at the same time he won't make a move; it must come from me. Should I tell him I am interested, and if so how? Speaking seems to be out. Etiquette: Note? E-mail? Anything? Someone help! Please. Do not want to seem weird or pushy. Shy. Time is Running Out :o(
