We would like to announce another new visualisation program for HEALPix maps. It is called Univiewer, and using it you can:
- Rotate and zoom maps on the sphere in 3D;
- Create high-resolution views of square patches of the map;
- Change maximum and minimum values of the colourmap interactively;
- Calculate the power spectrum of the full-sky map or a patch;
- Display any column of a HEALPix map FITS file on the sphere.
Univiewer was started last year as a student summer project for one of us (Shamil). It has reached a sufficiently developed state to be useful to others, hence this announcement.
The source code and binaries (Linux and Windows XP) are available from the web site:

Feedback (and bug reports) are welcome.
