Del desarrollador:
Spy allows you to run a small server on your Mac, that when accessed by any normal Web browser, allows people to see your screen, as well as information about your Mac.
But it doesn't stop there - they can look at a normal static image, or they can look at your screen, live, in real-time! You can also choose which image format you want to use - JPEG or PNG.
