Every element has a pretty side, and we've tried to give each one a chance to show off what makes it unique and beautiful.
For example, the noble gases are represented by discharge tubes that display their characteristic colors in an electric arc. Iodine was photographed while being heated from below to bring out the distinctive and lovely purple vapor it gives off at elevated temperatures. Niobium is represented by an ultra-high purity crystal ribbon, an attractive form that few people have ever seen. Silicon, in contrast, is represented by a relatively low-purity sample, but one that is just plain good-looking.

The poster is printed from a 1.4GB composite file with a resolution of 520 dpi (at 53" wide) on a MAN Roland 900XXL 73" sheet-fed offset press, the first of its kind installed in the US. Stochastic dithering (instead of conventional halftone screening) results in an extra-sharp image, aided by the high registration accuracy of the press. The images come from Theo's library of over a thousand element samples, many collected or re-photographed specially for this poster. (A few highly unstable elements show a picture of the person or place after which the element is named, or a mineral that contains trace amounts of the element.)

This poster is outstanding in its large format - it is over 2 feet high x 4 feet wide.
Actual poster dimensions: 27" x 53" (68cm x 134cm)

United Nuclear is offering the poster at $10.00 off the normal retail price.

3D (Lenticular) Periodic Table Poster

Another excellent & unique Periodic Table of the Elements poster from Theodore Gray.
Here's something you definitely haven't seen before...
This poster incorporates Lenticular technology that uses linear lens elements laminated over a specially processed image to display different views to each eye, creating a convincing stereo 3D effect. The samples appear to stand out from the surface.
Creating it required photographing every sample from 12 different angles. The prints measure
22" x 11.25" , the largest practical Lenticular size available... and they use a fine 110-lenses-per-inch screen. The Lenticular imaging layer makes the posters about 1/16" thick, which is similar to a plastic kitchen placemat in thickness but larger in size.  
The back side is filled with text giving the basic physical data about each element (atomic weight, melting point, boiling point, and density), and a three-line description of what each sample is, along with its approximate physical size. (Please note that while the print quality is very good, Lenticular technology necessarily limits the sharpness of the images.
(These prints are not quite as sharp as the large poster version above).
