D-Day exhibit at Bletchley Park

Rose Design did some really lovely work for the design of the 75th anniversary of D-Day exhibit at Bletchley Park.  The D itself was made from ticker tape; they used the ITA2 Boudot-Murray teletype standard to type the words “Interception Intelligence Invasion” (interspersed with NULs to make it more aesthetically pleasing):

I had hoped they’d encrypted the words with the Lorenz SZ-40 cipher, used by German High Command, which Colossus was created to break.  But ITA2 is certainly much cooler than A=1, B=2, etc.
