Have you looked at the work of Johannes Baagøe? Unfortunately his site went down a while ago, but someone made a copy of it on GitHub.

It has some analysis as well as JavaScript PRNG implementations.

Thanks for the pointer. This is pretty interesting.

It might be worth it to add Alea (and others) to seedrandom.

The standout was the Alea algorithm, which is impressively simple and fast. The PR has a direct port of Baagoe's code. It produces the same sequence for the same seeds as Baagoe's original.
