Halo Room
From http://www.presentations.com/presentations/technology/article_display.jsp?vnu_content_id=1000729992
While not a projection technology per se, the company's Halo Room ? a videoconferencing package ? is demonstrative of HP's approach to AV innovation. Each Halo Room is identical, with matching furniture, wall coverings, plasma displays and audio technology. During a videoconference, participants peer through the bank of plasma displays to a remote site indistinguishable from their own, generating a more realistic experience.
HP worked with Dreamworks.
~$250K to build the space - not including the equipment/software
Needs 40mbps stream between the two rooms
