What does WWT stand for I hear you ask? Well if it were for my reaction then it would be Wow Wow Treble Wow.
Really is stands for WorldWide Telescope which is a Web 2.0 visualisation software environment that enables your computer to function as a virtual telescope—bringing together imagery from the best ground and space-based telescopes in the world for a seamless exploration of the universe.
How about taking a 5 minute break and viewing a panaroma of a different city? Install WWT here: http://www.worldwidetelescope.org/
