Wink is a great little utility to make demonstrations about computer programs but it has other uses also. I used wink the other day to record the server load of our new terminal server. I set wink to capture 1 screen per minute and the refresh rate on the server load graph so that it would not refresh the whole graph in less than a minute. This way I could get a visualization of what the server load was like. Another great thing about wink is that it is free for personal or business use and works on both Linux and Windows.
