CipherSaber is a neat program based on the idea that everyone should be able to write their own encryption software in case governments ever made it illegal to sell. That probably won't happen, but it's fun anyway. I didn't invent it, I just made this version in Scratch. But I'm pleased with how it came out, so have a look.
