I have just watched the video now, it is really interesting experiment how a modeling program shows that.

Around a month ago had similiar idea in Xara but finally did not post in this format, wanted to place the extruded laptop in front of the mirror, then place a Xara screen inside on its screen, on which inside there is another and so on in the depth

But finally booked it as a not successful attempt and the 'project' stopped Did not like the table and neither was sure whether the mirror really works like that. Anyway 'Only Extrudes' everything in the file
