What library is used?

Is there a website https://www.dewanddoritos.com/
It has the effect that elements of the robot flicker. If you look at the resources on the website, there is picture and mask images, so there is some script goes obrabotka masks and the flickering white light.

Tell me what kind of library?

And tell me how this Glitch effect to do? This in-house?
