The concept of a ringworld is wonderful - Niven's story, not so much, yet good enough to entice me back into after the mega-structure on't otherside of the universe is currently topical (if indeed, anyone could use the term 'otherside' when talking about our curving and folding universe). Great fun for sci-fi week here on goodreads.
