This is an HTML5-based implementation of the esoteric programming language Wunnel.
Wunnel is a two-dimensional language which draws from the 1L family of languages and incorporates features from reMorse. The name is both a play on the pronunciation of "1L", and a recursive portmanteau of the words Wunnel and tunnel which is used to describe the long sequences of identical instructions (often nops) used in Wunnel programs to sync up remote parts of the program.
Select an example program from the drop-down (or click Edit and compose your own,) then click Run.
INP is highlighted in the instruction matrix, the program is
waiting for input. Click on the Input text box and input some
1s (Wunnel programs take bits as input.) The program
will consume them in order, and continue running.
