Grobe. Live radio On Saturday 29 March 2014, Radio 4 broadcast an adaptation in front of a live audience, featuring many members of the original cast including Stephen Moore, Susan Sheridan, Mark Wing-Davey, Simon Jones and Geoff McGivern, with John Lloyd as the book. The adaptation was adapted by Dirk Maggs primarily from Fit the First, including material from the books and later radio Fits as well as some new jokes. It formed part of Radio 4's Character Invasion series. Legacy Future predictions While Adams' writing in The Hitchhiker's Guide was mostly to poke fun at scientific advance, such as through the artificial personalities built into the work's robots, Adams had predicted some concepts that have since come to be reality. The Guide itself, described as a small book-sized object that held a great volume of information, predated computer laptops and is comparable to tablet computers. The idea of being able to instantaneously translate between any language, a function provided by the Babel Fish, has since become possible with several software products that work in near real-time. In the Hitchhiker's Guide to the Galaxy, Adams also mentions computers being controlled by voice, touch and gesture, a reality for humans today. "Hitch-Hikeriana" Many merchandising and spin-off items (or "Hitch-Hikeriana") were produced in the early 1980s, including towels in different colours, all bearing the Guide entry for towels. Later runs of towels include those made for promotions by Pan Books, Touchstone Pictures / Disney for the 2005 movie, and different towels made for ZZ9 Plural Z Alpha, the official Hitchhiker's Appreciation society. Other items that first appeared in the mid-1980s were T-shirts, including those made for Infocom (such as one bearing the legend "I got the Babel Fish" for successfully completing one of that game's most difficult puzzles), and a Disaster Area tour T-shirt. Other official items have included "Beeblebears" (teddy bears with an extra head and arm, named after Hitchhiker's character Zaphod Beeblebrox, sold by the official Appreciation Society), an assortment of pin-on buttons and a number of novelty singles. Many of the above items are displayed throughout the 2004 "25th Anniversary Illustrated Edition" of the novel, which used items from the personal collections of fans of the series. Stephen Moore recorded two novelty singles in character as Marvin, the Paranoid Android: "Marvin"/"Metal Man" and "Reasons To Be Miserable"/"Marvin I Love You".
