It seems I have a penchance for off topic thoughts this week. Again I found it via the BBC but I think this project to be highly exciting (to me at least :P). EStar is a way of people around the Internet gaining access to telescopes to watch the skies.
In other words (and over simplified) you have a bit of software on your desktop that uses a Perl middleware of objects that make requests to telescopes. And its GPL too.
I'll be downloading this later so if anyone wants a review of it let me know.
