note where the 'X's are. this is the rotor starting position. you can move them by first pressing 2, 3, or 4 (with 4 being the largest circle), then pressing the arrow keys. to encrypt/decrypt, follow the lines from circle 2, to circle 4, and then back to circle 2 when you are done, turn circle 2 clockwise. when circle 2 gets back to the starting position, turn circle 3 clockwise and so on eg.: the rotor starting position is a,b,c starting from 'a', follow the purple line to the red line follow the red line to the blue line follow the blue line to the yellow line ... you will end up on the letter 'c'. turn circle 2 clockwise so rotor 2 is above 'b'
this project comes from the book 'The Secret Life of Codes' by Kjartan Poskitt
