OK, it's working now. As Niven wrote in 1984, "'East takes you out, out takes you west, west
takes you in, in takes you east, port and starboard bring you back."
For color blind people: Check out Visolve, http://www.ryobi-sol.co.jp/visolve/en/. Gives you a windowport in which you can temporarily change the color, or a task tray icon to temporarily change the entire screen colors.
