Strange programming languages

I like esoteric and obfuscated programming languages like
Befunge a great 2D language
Chef in which programs are also delicious. Take a look at the program Fibonacci numbers with caramel sauce

I have written a lot of languages and compilers/interpreters. Some of them I have put online on this site:

Lambda: a combination of lambda calculus with neumann architecture which allows for self-modifying code
Hello: a program in which it is very easy to program a "Hello World" example
