Here is an EXOGLYPH (Exo = pop-up only, not depth). EXOGRAM L/R or R/L also possible of course.

Not a shoot at 45° like Phantogram is, EXOGLYPH (Exoglyphe in French) have a shoot more narrow vertical axes and really need to put flat on a table to see also with an axes over 45° if not subject much more distort.

Notice I discover first anaglyph made narrow vertical axes of some houses draw in a very old English book.
Later (but many years before Phantogram) with a 3D draw kit bought in US to a 3D shop (closed now since many years), also for aerial houses to draw in 3D.

The book and the 3D draw kit given to me idea to shoot more narrow vertical axes.

If you want an INTROGLYPH or INTROGRAM (INTRO = IN) depht only with special vertical axis too... see below our fish 2D to 3D conversion.
The eggs basket is also a conversion but EXO. Made for a children optical science kit editor "The power of light" SENTOSPHERE.
