Making better head bob?

I’ve been trying to figure out how I can improve my head bob animation. Right now, I’m just using sine for the animation on the X and Y axis. However, this results in a very linear motion that’s up and to the right, then back down and to the left. Not very good.

I was trying to figure out how I could get it to look more like a U shape, in terms of motion, as I think that’d be smoother. Not really sure algorithm-wise how I could accomplish that.

Thanks for any help.

Lissajous curves might be just what you’re looking for (these are commonly used to simulate sway when using a sniper scope).
