the eyetwig utility, with the webcam detects the head motion, and accordingly moves the mouse cursor. i used it to change the view i look at, but with fullscreen mode it does not work, does anybody know something that helps? i noticed that the cursor dissapears when fullscreen.can i make the windowed mode big enough so that it has full screen size?

You can maximize it just like any other window...just click on the button up in the corner, or just drag the corner of the window. You can also drag your taskbar down to give a little more room. It will be fullscreen except for the titlebar at the top.
