These are E8 related Science, Technology, Engineering and Math images laser etched into large optical crystals of varying shapes and sizes. The math is hyper-dimensional in that it is >3D. The images are "projected" into 3D using a math function called a "dot product".

Single color (white) or multi-colored LED light bases are optionally available. I also recommend using local h/w store under-counter lights as bases for crystals.

Each crystal has the email signature etched in the lower right corner of the main face.

Please inquire for custom shapes, sizes and projections of any object you see.

Your crystal comes with a quality gift box, ready for presentation. It is black satin-lined gift box with magnetic closure.
