What's your favourite esolang?

I'm looking for a new esoteric programming language to tinker with.

I looked at the esolangs.org wiki but there's too many to wade through, and the ones I did read were kind of pointless.

Any suggestions?

FRACTRAN at first sight is just a sequence of fractions, but it demonstrates that many registers can be encoded into a single number.

The FRACTRAN prime game has a certain charm.

Modern computers do computations based on a small number of simple operations, and Brainfuck demonstrates that number can be VERY small.

A BF Quine was a challenge.

Conway's game of life shows what happens when a finite state machine is fixed, and the programmer can only change the input.

I wouldn't even try to make a GOL program, but random configurations are interesting to watch.

I found an assembly language that has only 12 instructions that will run on a random access machine.

Less instructions would make simple tasks too long.

More instructions, and I may as well write in 8086 assembly.

Beatnik is kind of interesting, if I ignore the scrabble element and use numbers instead of words.
