The project is based on 16-bit Linear Feedback Shift Register but with a small twist - at each clock cycle the LFSR combines it's output from 2 halves, upper half (bits 15 to 8) is rotated left and the lower (bits 7 to 0) are rotated right and XOR'ed at the end.
Inspired by this StackOverflow post.
You can experiment with different initialization seeds and see how it changes the generated sequence - all 0 initialization does not work, the PRNG always returns 0s from such seed. The proposed usage of this project is as a noise generator that could be fed to e.g. musical synthesizer or be used as a non-cryptographic randomness generator.
