"I'm glad to hear that. How does going between frames work? Is there space inbetween? Is it a sharp transition? If different paintings are on different walls of a room, does going from one to another feel like going in a straight line or turning a corner?"

"Hm. I've never tried to explain it before. .  . It's not that there isn't a space between, but you can't really be in that space. It's like stepping from one rock to another in a stream, except you can't fall in the stream because it isn't anything. I've never noticed turning a corner to feel different, but going up or down the wall does. You still go out the side of the frame but in a different direction than aiming for the frame to the left or right."
