MAKE Your Own Auxiliary Display
One of the promises for Windows Vista is a collection of display options making it easy to add a second functional display to your system. Microsoft has previewed this stuff with options like having a second screen on the top side of your laptop, so you can quickly check appointments or change your song list without flipping open the lid. Another obvious use for this is system monitoring. In theory, you could quickly monitor vitals on a machine running with no monitor, without needing to make an RDC or VNC connection. Last weekend, PT posted a great how-to on making this work with technology available today. You need a Pocket PC to make it work, but this is a genuinely cool hack that could be useful in environments where KVM switching between multiple machines is common or if you just want to geek out your system.
