A *.pdf or *.jpeg of John's up-to-date Periodic Chart of the Chemical Elements customized with your name. This is suitable for use as a screen saver or as a reference graphic to learn about the chemical elements. This Periodic Chart graphic will be hi-rez making it suitable for enlarging so that individual element's boxes can be made full-screen and even projected for classroom use. In addition, the high resolution of the file makes it possible to be printed to its full, intended size of 42" x 28" in a large format printer. When printed on glossy paper (especially with UV-resistant ink) it makes a truly impressive wall chart.
