Interpreter for the programming language Brain---- (can't say the proper name because it's blocked, for good reason) I wrote in an hour. It has only 8 instructions! (they are + - < > [ ] , and .) Pressing C will let you add an instruction or many instructions. Pressing R will clear all instructions in your code. Pressing the green flag will run your code. It comes preloaded with Hello World! Side note: using , is broken as Scratch is not case-sensitive.
