Look Around You‘s Periodic Table [ed: updated link]
Only feeling a bit miffed, cos I did something like this some years ago myself. When you find yourself bored editing a science textbook, have access to Adobe Illustrator and an EPS of the periodic table, the product is inevitable really. Anyway, they have a DVD coming out soon, hooray. (Note to self, get DVD player for Xmas)

“Each ‘DVD’ measures approximately 70 inches in diameter and weighs around 600 kilogrammes” – from the site

Made up elements also came up when sitting bemused at the fantastic nonsense you get in the starting credits of Sapphire and Steel. “Transuranic heavy elements may not be used where there is life.” rumbles the god-like narrator, “Medium atomic weights are available: Gold, Lead, Copper, Jet, Diamond, Radium, Sapphire, Silver and Steel. Sapphire and Steel have been assigned.” OK, FIVE* of those actually are elements, but, sad man that I am, watching these shows, I’d be shouting out “Perspex, Lard, Wheat, Toothpaste. Perspex and Lard have been assigned.”

*edit, not four. (as any fule can see)
