Ruby Compiler Project

In my spare time (that is, apart from all the other hobbies I have), I have started work on a new programming project. My goal is to write an interpreter/compiler for a new programming language. I have no great ambitions, this project is purely for my own enjoyment and to hopefully teach myself something new.

Goals/Plans:

1. Develop in Mac OS X
2. Implement the compiler in Ruby
3. Use test driven development and the agile process
