[AstroBetter](http://www.astrobetter.com/) has an article on on a [FITS QuickLook plugin](http://www.astrobetter.com/apps/qlfits-the-quick-look-generator-for-fits-files/) for Mac OS X by the author of the plugin. Looks incredibly useful if you use a Mac and FITS files. QuickLook plugins for more scientific data file formats would be really nice. Any one have an HDF 5 plugin?
