Use Your Ipod Touch/ iPhone as Wireless Monitor
This is also great if you have an old laptop, to make it faster use a cat-5 (ethernet) cable.
All you need is:
iPod Touch/ iPhone- with vnc client (I use VNC lite)
Step 1: Screen Recycler
It will ask if you want to buy it, I didn't I clicked Buy Later, the demo mode is unlimited but you only have 20 minutes a go.
Take note of the ip address and the port.
Then go to the ipod/iphone and type the ip address on the screen recycler window and change the port (if necessary).
(6900 is the default port)
Step 2: Finished
It is great for those with a Macbook or other that has only one display out and want more than one.
