I have the following at hand:
1. Stage blood capsules for, like, blood effects across the wall behind me. Sometimes I let it drip off my chair so it pools beneath, or maybe running down my arm so it gets into the keyboard.
2. A bucket of builders’ rubble from which I can sprinkle detritus over myself and the keyboard.
3. Pipe tobacco + pipe (duh!).
4. A foot-spa converted into a portable trench. This is where I keep my gaming boots and socks.
5. I also uninvented deodorant and changed my soap for something that stings.
6. Switched off the central-heating.
More ideas?
