With over 70 exhibits, the Museum of Illusions has the largest collection of holograms, stereograms
and optical illusions in the entire Middle East.
The Ames room, stereograms
, the mirage and the infinity room are some of the attractions on display.
The Museum of Illusions has the largest collection of holograms, stereograms

McDowell Packaging's new Digital Combination blends traditional brand augmentation technologies including foil stamping, micro embossing of stereograms
, rotary screenprinting, doming and tactile features driven by a digital print engine.
The works show the diversity of creative holographic techniques devised over the last 30-some years, spanning sophisticated layered and multi-exposed transmission holograms to achromatic stereograms
and--of course--digital visualisation techniques.
The tests were conducted using a methodology called unfakeable computer-generated random dot stereograms
, in which the subject is presented with 2 random dot patterns, one to each visual field independently (ie, left and right eyes), through a stereoscope.
A graduate of Princeton University, one of Toch's first studies was to look at the effects of violent and nonviolent stereograms
--realistic images of violent and nonviolent acts--on law enforcement students.
Depth inversion despite stereopsis: The appearance of random-dot stereograms
on surfaces seen in reverse perspective.
A time before Ipod and mp3 recordings - when people listened to music on newfangled devices called stereograms
This is most often done by the use of stereograms
These components of the examination were stereo acuity as measured by random dot stereograms
(RDSs) using the Randot stereotest, near point of convergence (NPC), ocular alignment at distance and at near determined by cover test, distance phoria (lateral and vertical) and gradient accommodative convergence/accommodation ratio using the von Graefe technique, and the amplitude of accommodation (AOA) measured by phorometry using the minus lens to blur method.
Their topics include combinatorial figures, binocular vision and single image stereograms
, distortion and anamorphic art, spherical polyhedra, and matroids.
