When you fold the US $20 bill in a specific way,
an effect is created that is just down right weird.

One has to wonder about the shock of the first person
to fold a $20 and "see" a chunk of recent history.

Turn a new US $20 around to look like this:

Fold it in half:

Fold this in half again:

Open it up again:

Fold the right hand corner toward the center,
matching the crease on the long bottom,
with the crease in the middle,

Repeat the folding of the left side:

What do you see?

Twin Towers Burning?

Now, turn the bill over, maintaining the folds:

What do you see?

Is that the Pentagon?

Weird?
