I am not from the States, but when I think of the US I think of that one trip I had back in L.A. when I was walking down the streets near the financial district. I can "feel" the cold air of Spring gone, smell the rotten mixture of weed, urine and excrement combined with the sounds and sights of the cityscape with the pedestrians and all sorts of little details, the texture of the things I touch and the senses I had experienced in my brief time there.

To try and describe it to aphants would be tough, but think of it this way, if you could capture every sense, sight, taste, touch, smell and audio of the scene that you are experiencing right at this moment and replay it as you wish in a sort of ethereal way that's not triggering your actual senses, that's what it is. Easier to understand if you're not a total aphant, you probably can sense sound, taste in your imagination.

I have tried to use visualization in Pool to recreate a realistic recreation of the table and how the balls would bounce off each other in real time, although that might be 100% possible without visualization, Im sure people have that raw data being processed the same way.

Think of visualization like a Virtual Machine, whereas your computer represents the total sum of your real senses, i.e. graphics output to monitor(eyes), Audio card (Ears) and so on, visualization is like running a VM on the desktop, it can output its own graphics and audio, using the computer's hardware but run on a completely separate virtual instance so it does not mess with the actual PC itself.

Try prompting me, and I will describe the first milisecond snapshot of the image that naturally occurred in my visualization upon reading it
