This script was tested in two different computers to make sure it produces the same results.
A Befunge interpreter could be put in the same script, but I decided to Keep It Simple: Here is the Python 3.0 script that converts seed programs to Befunge. It is not currently known whether any such seeds exist, but it seems likely. All that would be required, therefore, would be a seed that generates a program whose prefix looks at the length the program as a whole, and interprets the resulting number as a program in some Turing-complete language, executing it programs could then be compiled into Seed via hardcoding the seed itself, and specifying what program to execute via varying the length. It is probable that Seed may be Turing-complete in a more traditional sense, too there are infinitely many possible Seed programs, because nothing prevents the creation of a program that's larger than the Mersenne Twister's period (and repeats itself as a consequence). (ℒ-hardness can be thought of as being a form of Turing-completeness.) Although that means that it is not possible to generate every possible Befunge program, it has been proven that Seed is capable of generating interpreters for Turing-complete languages, and thus is ℒ-hard. The Mersenne Twister has a period of 2 19937 - 1.
