The coolest thing there? A fully playable version of the original Infocom
Hitchhiker's Guide to the Galaxy game, designed and written by game design legend Steve Meretzky. Like all Infocom games of that era, the Hitchhiker game is text-only. However, the BBC held a contest for amateurs to illustrate the game, and the two winning entries are both available to play.
