I think I can do that by creating anamorphic distortions and/or stereograms. Or at least I could challenge the space inside viewers' heads through these tricks, which I can now conjure with software:
- Anamorphme
- Easy Stereogram Builder (web based SIRDS)

Erhard Schon, who once lived with Duer, did anamorphic woodcuts in the 1500s:
Head on view
Same woodcut as above,
viewed from a very oblique angle
showing a different scene
The Schon woodcut looks very different from an oblique angle -- than it does from the head on view (another example at this link). An artist could warp physical space, by blowing that image up to the size of a mural. At least he could change the perception of that space in front of a mural with anamorphosis.
I would love to squeeze 3 images from the same mural -- one image from the head on view, one from the oblique left angle, and another completely different image from the right view. The 3 different (objective) perceptions would mentally separate 3 different visitors in front of the same image (and would essentially partition the room without walls, into 3 different spaces). David Alfaro Siqueiros achieves this with his "polyangular perspective," which is basically a variation of anamorphosis.

as it also leans left, from seating on the right)
"On the flat ceiling he painted an allegory of the Apotheosis of S. Ignatius, in breathtaking perspective. The painting, 17 m (55.7 ft) in diameter, is devised to make an observer, looking from a spot marked by a brass disc set into the floor of the nave, seem to see a lofty vaulted roof decorated by statues, while in fact the ceiling is flat"
Julian Beever does beautiful anamorphic chalk drawings these days:
An artist can also challenge the spectator's space with both random dot stereograms (RDS) and autostereograms (SIRDS). Both kinds of stereograms subvert a viewer's binocular vision, to deliver a spatial illusion when he crosses, or separates, his eyes.
I am more interested in marrying 2 images to conjure an unknown spatial illusion/object -- ie, using random dot stereograms

Distance Illusion -- Lincoln in Dalivision. From afar the image looks like Abraham Lincoln. From up close it looks like a naked woman looking out the window:
"The stones are placed so that the entire composition cannot be seen at once from the veranda. They are also arranged so that when looking at the garden from any angle (other than from above) only fourteen of the boulders are visible at one time. It is traditionally said that only through attaining enlightenment would one be able to view the fifteenth boulder."
Chichen Itza adds an element of time to change the space. Two days a year only, the shadows on El Castillo pyramid create the illusion of a serpent slithering down the slope.
"During the spring and autumn equinoxes, the late afternoon sun strikes off the northwest corner of the pyramid and casts a series of triangular shadows against the northwest balustrade, creating the illusion of a feathered serpent "crawling" down the pyramid."
This flat fresco mural by Pozzo
looks like the inside of a dome,
when seen from a single particular spot.
Unlike Siqueiros' polyangular murals, the "dome" by Pozzo decays into awkward distortions when seen from any other point in the church, other than that marked by a brass disc. Pozzo delivers only one image, Siqueiros aspired to deliver several images.
Other anamorphic examples:

Dual random dot stereogram
by Bela Julesz
The 3D illusion above does not exist without both of the random dot squares. Thus, I can marry the right square with a 3rd random dot square to create a completely different 3D illusion. Likewise, I can marry the left square with a 4th random dot square to create yet another different 3D object.
I thought about creating some kind of sculpture with the stereogram pair. Perhaps one square could be very large, but very distant. The other square would be small and close. When a viewer stood in front of the 2 squares, at the point where they looked of equal size (sitting next to each other), he could cross, or separate, his eyes and bring about the 3D illusion.
What if one, or both of the random dot squares were anamorphic?
The random dot stereograms (RDS) look like QR codes.
ie a random dot stereogram (RDS)
Could one marry an anamorphic QR code with it's pair, to create a stereogram? An anamorphic QR code stereogram?
Other objective illusions:
Looks like Lincoln from afar
Looks like a naked woman from up close
Dali based his painting on a distortion of the Abraham Lincoln portrait on a $5 bill, done by Leon D. Harmon. Later the technique became known as "photo mosaic" (AndreaMosaic software).

Value Illusion:
I would like to "sculpt" space, like the Japanese did in the Ryōan-ji zen garden in Kyoto:
Ryōan-ji zen rock garden in Kyoto
I would like to divide an open space, without building walls, but rather employing tricks like anamorphosis, photomosaic, and stereogram techniques. That way I can separate visitors in the same room by manipulating their perceptions. What one individual experiences visually from one spot in the room, would be completely different from what another visitor experiences from a distant spot in the same room. It would be like creating parallel universes under a single roof.
Chichen Itza in the Yuctan
The serpent effect observed during the 2009 spring equinox
Could we create harsh shadows, here in the Southwest, that make random dot stereograms? If so, that experience would be limited to only a few times a year, during a particular time of day.
One can also sculpt space with sound. The Exploratorium in San Francisco has two huge parabolic concrete reflectors (really just domes on their sides) facing each other, on the opposite sides of a very large room. Two people sitting in the focal points of the dome can carry on a conversation without raising their voice, even though they are so far away that it's hard to see the other's face. However, other people cannot eavesdrop from any other point in the room. In this way the space is ruptured and warped, as 2 distant points are connected in the room, to make a small intimate sound space.
Exploratorium
"The LISTENING VESSELS consist of two large parabolic reflectors set at least 50 feet apart which act as mirrors to reflect sound from one to the other. Two people sit opposite each other at approximately the focal point for each reflector, so that the sound coming from each reflector is focused at this point, allowing each visitor to clearly hear the other's voice in spite of the distance separating them or the noise in the museum."
The "only theatre of its kind in the world,
pioneering the exploration of space in music.
The theatre's 169 speakers bathe listeners in sounds
that move past, over, and under them.
"Sound sculptures" are performed in darkness
in the 49-seat theatre."
