Cylindrical panoramas covering at least 120 degrees

Most lenses use a rectilinear projection that keeps straight lines straight, but the widest rectilinear lenses barely cover 120 degrees and the projection becomes quite unnatural at that angle. In contrast, wide panoramas used to be captured by special cameras that rotated a slit and lens assembly during exposure, yielding a cylindrical projection that bends horizontal lines, but looks reasonably natural covering up to 360 degrees. Now, fisheye images or sets of rectilinear images can be computationally transformed into cylindrical panoramas... and you can enter your best here.
