Just to add, there's a direct link back to DoTT / MM as well, as Thimbleweed Park is the brainchild of Ron Gilbert and Gary Winnick, the developer and artist behind the original games at LucasFilm (they were involved with Monkey Island as well).
Completed Thimbleweed Park over the Easter break and it's fantastic.
(lacking some graphs, though, which is the most interesting of the article)
