Brian Moriarty's Loom is a masterpiece. An utterly original fantasy adventure built around a unique music-playing mechanic that also happens to be one of Lucasfilm's most beautiful games ever released. A game the definitive version of which was released for the exotic FM Towns and one you can bid on via this eBay auction for the rare and coveted Loom (FM Towns).
The game comes complete in its box with data CD, audio CD, manual, hintbook, hint viewer, spellbook and registration card. Everything seems to be in excellent condition and the seller's shipping worldwide.
Oh, and here's an excellent postmortem on Loom.
