Okay, I am greenie when it comes to SF0, so go easy on me. My initial approach is to over analyze the tasks hoping it will inspire a cool idea. That is definitely what happened here. The phrase 'does not exist physically' really got me. It brought me back to all of those crazy philosophy classes from my undergrad. Late nights hammering away on my laptop reading Modern Philosophy.

I got to thinking....

It is arguably so, that everything, once thought, then exists, even if only as an idea. This cannot be proven true or false either way so maybe it is a waste of time to even mention it. However, to explain my map I think one must keep this in their mind and sheer impossibility of truly completing a task such as this.

Mapping something that does not exist would then mean that the map needs to come in to existence without having been thought about. This is my attempt at precisely that. Mapping a recollection of uncontrolled thought, in this case a daydream. The only restriction i gave myself were my materials: watercolors, sharpie, paper. The following is a picture at which I arrived.

Don't give it too much thought.
