Well, I'm stumped: Let's play The Sense of Connectedness

I just recently downloaded an indie game called The Sense of Connectedness, and even though I just finished playing it I'm still not entirely sure what to say about the damned thing. It's just one of those games the resists explanation.

What I can say for sure is that it is fiendish in both its complexity and simplicity, and after plugging away at it for about an hour I think I almost understand it. It's confirmed that there is an "end-state" to the game, but I haven't found it. So, fellow tropers, I turn to you: Can you make heads or tails of the game? Get it here, and please make liberal use of spoilers, as most of the fun comes from discovering things for yourself.

Any tips on how to get to PSI? I think that might be key, but I have no clue how to rearrange memory to open a path. Also, I think SOUL might be an important part, because it brightens any electrons that enter it. Other than that, I've got no leads.

We have a dedicated Let's Play forum here.

Oops! My bad. I didn't actually intend to make a let's play thread, I was just stumped for a title.
