UltraVNCis an easy to use, fast and free sotware that can display the screen of another computer (via internet or network) on your own screen. The program allows you to use your mouse and keyboard to control the other PC remotely. It means that you can work on a remote computer, as if you were sitting in front of it, right from your current location.

If you provide computer support, you can easy access your customer's computers from anywhere in the world and resolve helpdesk issues remotely ! Your customers don't have to pre-install software or execute complex procedures to get remote helpdesk support. UltraVNC allows you to remotely control a computer over any TCP/IP connection.

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.
