halowall experienced

It is impossible to photograph someone else's experience of HaloWall, because their rainbow is visible only from their vantage point.

 

So watch for the moment when I pass behind them -- you will see a rainbow that is similar to what they are seeing. They are much closer to the wall so they are seeing circular rainbows that are two to three feet in diameter, tightly encircling their heads.

 

But neither can these two people see what the other is seeing.
