New CD and power point available

All, I have now completed the "Break Enigma!" CD This is a bringing
together of a lot of disparate bits on my web site into one product with
original cipher texts to break and simulation tools to do it.
It is available from my web site: www.codesandciphers.org.uk 

I also now have a 55 element Power Point DVD presentation about the
breaking of Lorenz and Colossus. It is illustrated by a lot of 2 minute
video sequences showing the breaking, on the rebuilt Colossus of a
cipher text and its decipherment on virtual Tunny.  
I am happy to make this available to anyone wishing to show it to
students or technically interested groups.
It does need a DVD reader and suitable codecs to show video on a 
projector.
