BrainF*** is a programming language that only contains the characters:
< > + - , . [ ]
COW only contains 12 commands, each written as MOO's:
moo
mOo
moO
mOO
Moo
MOo
MoO
MOO
OOO
MMM
OOM
oom
*These are of course all case sensitive*
Upon further research into these languages I came across this site: http://www.bigzaphod.org/cow/
And with it, a worrying thing arose to me. There were no stable compilers or interpreters for this great language.
Bare in mind ("rawr"), that at this point I had yet to even write a program in COW, but none the less I was enthused by how such a simple architecture could still have a modern day application, given that COW, and BrainF*** alike are based off of the old Tape Driven computer Systems, where a Command Tape drives the position and data stored in a Data Tape.
