If you want a live illustration in a computer, you might pick down Scala 
<http://www.xs4all.nl/~huygensf/scala/>.
It can play all sorts of 
scales, but do something simple:

Start the keyboard "play", select notation system E12 (12-equal 
temperament), and set "Scale preset". You now have a standard piano 
keyboard. Select mode, and chose
   2 2 1 2 2 2 1 G.Lydian, M.Ionian, M.Hypolydian, Major...
Now, only the major key notes on the keyboard are highlighted. Then 
change the "first degree" number in the mode window, and you can see how 
the major key slides through all possibilities.

The only problem here, relative traditional key signatures, is that the 
flats and sharps are named quite arbitrarily. The reason is tha the 
notation derives from not from 12-ET. So if you want to get that 
illustrated, choose say E31.

Have fun.
