Info for tech-freaks: These panoramas were made with Apple QTVR authoring studio 1.0.1. First seven 35mm images photographed with a Nikon FM2 with a 20mm lens are stitched together to a digital panorama. Then the panorama is cut into tiles and the program makes an QTVR-panorama of them. The QTVR-panorama is a special quicktime-movie, which can be viewed with the right quicktime-player. With Quicktime 3.0/4.0 and the QT-plugin for your browser, you should be able to zoom and pan the panoramas. Enjoy!
