I did this in high school. I hosted an SSH server at home on port 443 so it'd get through the school's filtering, then tunneled in and connected with VNC.
Only time I got yelled at was when the teacher saw the SSH window open and yelled at me for being in the command line. So I changed the colors to black text on a white background and they never said anything again.
