One of the first things we learn about computers is that they perform operations using binary code to represent values. It's a fundamental trait of computing -- but it's not a requirement.

The Bank of England slipped a hidden binary code in the design of the new £50 bill which features computer pioneer Alan Turing. Here's how to decipher it.

That design isn't all however, as there's also a hidden message. Buried in-between parts of BioWare's message are 1s and 0s of Binary code. Put together, it spells out a single word: Epsilon.
