Just like a WI??O?

The answer to this puzzle is a single word.

• Looks cool. May be a dumb question, but do the tiny white stars and dashes on the borders of the red squares mean anything for the puzzle? Or can they be ignored?

The word is:

Reflection

Because:

The second image is a grid of mirrors/walls that reflect a ball sent in from the left (hinted at by the first image):

The third image can be divided into a four-by-four grid of squares, each of which is a 3x3 pixel font letter. And reading those in the order of squares that the ball crosses gives us the answer:

And the title:

Hints (if we reflect it vertically) that the answer is just like a MIRROR!

• What's going on with the R, the T and the N? The T and N are upside down, and the R is just a backwards L when looking from the other side. The rest of the letters look correct when looking from the other side (flipping along vertical axis). btw +1. I didn't know there was a 3x3 pixel font!

• @JLee I think the letters should be viewed/reflected based on the direction the ball is travelling, but couldn't quite work out a consistent explanation.

• @JLee Looking at it again, a simpler explanation may be that the letters in the bottom half are also reflected vertically. (Not that you can tell with the I and O)
