this article provides tips on how to use device orientation information in tandem with css 3d transforms.

...hose values: the initial alpha value is 180 (device flat on the back, top of the screen pointing 12:00), so the rotatez value should be alpha - 180 the y axis of the screen coordinate system is inverted, such that translatey(100px) moves an element 100px down, so the rotatey value should be -gamma finally, the order of the three different rotations is very important to accurately convert an orientation to a 3d rotation: rotatez, then rotatex and then rotatey.

because the intensity of diffuse light depends on the angle of incidence (the angle between the vector representing the direction from which the light reaches the surface and the surface's normal vector or the vector perpendicular to the surface), the intensity or brightness of the light reflected by an object varies depending on the surface's orientation relative to the light source.

Web accessibility for seizures and physical reactions - Accessibility
"a pattern with the potential for provoking seizures contains clearly discernible stripes, numbering more than five light-dark pairs of stripes in any orientation" in addition to stripes, checkered patterns have also been known to cause photosensitive seizures, according to cedars-sinai.
...other disorders, such as disorientation, nausea, vomiting, and more can also be so severe that the user is unable to function.
...for example, the page for trace research & development center’s photosensitive epilepsy analysis tool notes that “photosensitive seizures can be provoked by certain types of flashing in web or computer content, including mouse-overs that cause large areas of the screen to rapidly flash on and off repeatedly.” other physical reactions nausea, vertigo (or dizziness), and disorientation are very nonspecific symptoms associated with all kinds of diseases and not particularly suggestive of seizures (except maybe disorientation, which is seen in seizures).
