In my office, at work, which I never actually go in to, I have a wooden bowl containing five plastic potatoes.
I have a lava lamp.
I have a Lite-Brite.
I have a wooden Vietnamese croaking frog.
I have a 2016 Cattle Mutilators wall calendar.
I keep thinking about taking in my TI-99/4A and my one remaining CRT-based TV and hooking them up and leaving them on my desk, just to confuse people.
Office as performance art.
