Mimic implements a sick, sick idea floated on Twitter by Peter Ritchie: "Replace a semicolon (;) with a greek question mark (;) in your friend's C# code and watch them pull their hair out over the syntax error."

There are many more characters in the Unicode character set that look, to some extent or another, like others – homoglyphs. Mimic substitutes common ASCII characters for obscure homoglyphs.
Fun games to play with mimic:
• Pipe some source code through and see if you can find all of the problems
• Pipe someone else's source code through without telling them
• Be fired, and then killed
What arseholes. What magnificent arseholes.
