Collaborative virtual environments are multi-user virtual realities which actively support communication and co-operation. This book addresses the theory, design, realisation and evaluation of such systems, with a particular emphasis on support for large numbers of distributed users. A broad approach is taken, which ranges from the sociology of interpersonal communication to the management of communication in distributed systems. The emphasis on multi-user environments distinguishes this book from the many general books on virtual reality which only deal with single-user systems. This book presents: models of multi-party awareness and interaction in space-based systems; detailed designs of two prototypes (MASSIVE-1 and MASSIVE-2); experiences with collaborative virtual environments created using these; and analyses of the corresponding network requirements. Many of these results and ideas are applicable to other systems and approaches.

The beautiful Casablanca star, the world's greatest war photographer, and the secret love affair that would change their lives forever . . . in Chris Greenhalgh's "Seducing Ingrid Bergman"June 1945. When Ingrid Bergman walks into the lobby of the Ritz hotel in Paris, war photographer Robert Capa is enchanted. From the moment he slips a mischievous invitation to dinner under her door, the two find themselves helplessly attracted. Played out against the cafes and nightclubs of post-war Paris and the parties and studios of Hollywood, they pursue an intense and increasingly reckless affair.But the light-hearted Capa, who likes nothing more than to spend his mornings reading in the tub and his afternoons at the racetrack, is not all that he seems. And Ingrid offers the promise of salvation to a man haunted by the horrors of war, his father's suicide, and the death of a former lover for which he blames himself. Addicted to risk, Capa must wrestle his devils, including gambling and drink, and resist an impulse to go off and photograph yet another war. Meanwhile, Ingrid, trapped in a passionless marriage and with a seven-year-old daughter to bring up, must court scandal and risk compromising her Hollywood career and saintly reputation if their love is to survive. With their happiness and identities at stake, both Capa and Ingrid are presented with terrible choices.

Soon to be a major motion picture
Coco Chanel and Composer Igor Stravinsky.
Their love affair inspired their art.
Their art defined an era.
In 1913, at the premiere of Igor Stravinsky's "Rite of Spring," the young couturiere Coco Chanel witnesses the birth of a musical revolution- one that, like her designs, rips down the artifice of the old regime and ushers in something profoundly modern. Seven years later, she invites Stravinsky and his family, now exiled from their Russian homeland, for a summer at her villa, and the powerful charge between them ignites into a deep love affair. As Stravinsky enjoys a new burst of creativity and Chanel brings forth her own revolutionary creation-the perfume Chanel No. 5-their love threatens to overtake work, family and life.
