Ellen Spertus writes "Interactive Pictures Corporation (IPIX) has been threatening anyone who distributes software to create 360 degree panorama images, including free software developer Helmut Dersch. While Dersch's free tools (including a Gimp plug-in) are back online, he has had to remove information about creating high-quality panoramas. Meanwhile, IPIX, which charges $25 per panorama created, is preparing for its IPO. Read all about it. If you haven't seen 360 degree panoramas (outside of RL), take a look at Virtual Parks (requires free plug-in) or Sydney Olympics 2000 panoramas (requires free plug-in or Java). "
