PanoSalado is an open source Flash based player/viewer for cubic, equirectangular (spherical), cylindrical and QTVR panoramas.
It supports 2D & 3D hotspots, audio, video, and being extended via XML or directly via Actionscript (AS3). PanoSalado is based upon a (modified) Papervision3D core, and like Papervision is open source.
