Created by me and my personal favourite. This is a 2D language that uses Unicode box-drawing characters to create programs that resemble flowcharts, but the semantics are actually closer to that of a functional language than an actual flowchart. It has only five built-in operations (NAND, shift-left, less-than, function invocation and lambda expressions) and only one datatype (the arbitrary-size integer) and all the useful functions are implemented in terms of this. There is an entire library of functions for arithmetic, string handling, lists and lazy-evaluated sequences.

Example: The Factorial Function

 ╓───╖ ║ ! ║ ╙─┬─╜ ┌───╖ ╔═══╗ ┌─────┴─────┤ > ╟──╢ 2 ║ │ ╘═╤═╝ ╚═══╝ ╔════╗ ┌───╖ │ │ ║ −1 ╟──┤ + ╟─┴─┐ │ ╚════╝ ╘═╤═╝ │ │ ┌─┴─╖ │ ╔═══╗ │ │ ! ║ │ ║ 1 ║ │ ╘═╤═╝ │ ╚═╤═╝ │ │ ┌─┴─╖ ┌─┴─╖ │ │ │ × ╟──┤ ? ╟──┘ │ ╘═╤═╝ ╘═╤═╝ └─────┘ │
