About Wobbly I:

This sequence is based on a sequence first described by B. Reznick. It seems to wander around a bit unpredictably, beginning like this: 0, 1, 1, 0, 1, -1, 0, 1, 1, -2, -1, 1, 0, 1, 1, 0, 1, -3, -2, 1, -1, 2, 1...

Like many of the other sequences here, this sequence is self-similar; it contains infinitely many copies of itself and is invariant under scale. If you create a new integer sequence by using every other term of this one, you end up with exactly the same sequence!

The recursive formula for this sequence varies depending on whether each term is even or odd, causing the somewhat unpredictable behavior of the terms.
