Scoble recently had a wee cry about a new Microsoft Research project called World Wide Telescope that he saw prior to it being announced.

Well, today I got a chance to check it out at our TechFest (where Research show off all the stuff they do) ... and I have to say it is one very cool application.  Mind blowing ... and for the right person ... is likely to make them very happy ... and possibly cry (if they were alone and didn't want to lose face).  I kinda like space and astronomy ... so it was very interesting indeed.

You can check it out here: http://www.worldwidetelescope.org/

PS: you cant download it .. yet ... but soon you will be able to.
