After thinking about it for many years, I finally started writing a spec and a proof-of-concept implementation for my 2-D control flow programming language BOUNCY. The code isn’t yet ready for release, and there will be some further changes and additions to the language, but I thought I’d invite comments.
Although I thought the idea was original, Wikipedia reveals that there are other similar languages such as Befunge. Some of these langauges seem to have been designed with deliberate intention to be obscure, but that isn’t really my intent with BOUNCY.
