Many magazines have employed "guest editors" in recent times - CR included. The October issue of Wallpaper*, however, goes a step further and recruits three of them: Dieter Rams, Hedi Slimane and Jeff Koons.

The term "guest editor" is employed somewhat loosely - in fact, each of the three has been given 20 pages and a cover to play with. Rams uses his allotment to present his ten commandments of good design in a beautiful 16-page Matthew Donaldson photo-shoot of his favourite products (all designed by him, of course). The rest of the pages are taken up by a conversation between the master and Japanese product designer Naoto Fukasawa.

Slimane takes an entirely different approach, creating 20 60cm x 40 cm posters using his own photography and typography. Koons, typically, makes the most bizarre contribution - a 16-page artwork inspired by his passion for legendary rock band Led Zeppelin. Koons apparently commissioned "a leading cultural theorist to deconstruct the Zeppelin myth" to inform the work, which is well-timed seeing as the Zep have just announced that they are getting back together - spooky or what? In conversation with Stella McCartney, he also discusses the nature of fame, becoming a brand, and, err, vaginas.

Each has also produced a cover, so that three alternate versions will be available.
