I have started looking at the concepts of kinetic walls and came across this video:
this concept looks fascinating to me, how would i go about building it on a smaller scale? im guessing it involves motors ofcourse but how would the programming and tracking the person work?
Using LCD screens could be interesting to investigate.
you could have distance sensor hidden in the wall as well and they activate the motors for each tile that is in front of the sensor if there is something detected within x meters
(the guy opening his arms is probably a fake, it seems he is moving the arms in coordination with the tiles that are just moving)
Read all of this, and then decide if you still want to go ahead.

Daniel Rozin builds artworks like that, using servos and stepping motors: Daniel Rozin - bitforms gallery
"Wooden Mirror" has 835 moving wooden tiles: Interactive art with wooden mirrors - The wooden mirror (1/4) - YouTube
My guess would be one servo behind each flap. You can control 16 servos using a PCA9685 chip:
You can put up to 62 of these boards (992 servos) on the I2C bus. You can get servos from AliExpress.com for about $1.50 each and the driver boards are $15 so figure about $2.50 per pixel.
The display you show is in a 15x28 grid so 420 possible pixels. Of those, 86, if I counted correctly, are not populated. That leaves 334 active pixels. Figure about $900 for the hardware.
The use of servos is highly discouraged, because cheap servos don't last.

Indeed, Rozin comments in one of his videos that his early works had to be completely rebuilt, substituting steppers for failed servos.
I'm in the process of building one with 112 servos and 16-cannel driver interface as johnwasser has suggested.
So many steppers are complicated. I did use your boards, which you kindly sent me, but they should be redesigned to suit this project or my other projects. Are you willing to please share your design of the boards with the TPIC6B595's ?
So many steppers are complicated.
But they run for a long time. Your servo project won't.
Looks interesting, but a bit too busy for me.
I wonder what servos were used, and how long they lasted.
