Not literally sideways; I’d imagine a fair few people do that.
I’m talking sideways as an analogy for different from the norm. For example, I haven’t slept for over 24 hours; I’m working on a music video for Lovecraft, and as it’s all shot on greenscreen, I’ve estimated it’ll need about 150 man hours, not including rendering. However, I also have three other projects on, not including planning the new Howard Be Thy Name show; so I’d like to get it done in the next 5-10 days. This is where sleeping sideways comes in.
