Rivulet: A Flowing Strand Programming Language

Rivulet is a novel programming language that uses semigraphic characters representing 'strands' to write code. Programs consist of tightly packed code blocks called glyphs, each containing several types of strands that execute together. Rivulet avoids traditional control flow mechanisms, instead using a rollback mechanism to implement conditional branching and loops. Data is organized as lists, and commands operate on single cells or entire lists. While its syntax may seem complex at first glance, it's actually quite easy to learn.
