Pretty cool thing to show off to your friends.
Note that it is for entertainment purposes, good luck trying to pwn anyone forrealz with this setup.
To get this, download an app on your computer AND your iPad called Splashtop. It’s free on the PC and $2.59 (I think) on the App Store (alternatively, get it off Installous).
Make sure you are connected to the same network, and get your iPad to search for computers. Connect it up. Done 🙂
