Look! is a sound-based esolang based on brainfuck by User:None1. Its name has nothing to do with the specification of the language.
Commands
| Note | brainfuck |
|---|---|
| C or D# | + |
| D | - |
| E or A# | , |
| F | . |
| G or G# | > |
| A | < |
| B or F# | [ |
| C# | ] |
If there were multiple tracks in the sound file, Look! picks the first one.
