The current issue of Tightrope contains information on the 1995 German Multimedia Congress 1995 and past issues of the journal with interesting commentaries on the arts, philosophy and science. Bilingual reviews (German and English) focus largely upon broader issues in virtual reality and computing (e.g. 'The Architecture of Virtual Space in the Internet' by Jens Geelhaar), though some writers discuss their own work. Regrettably, the 'current' issue is somewhat out of date.
