The email box shakes violently if you stick around for a bit. It almost seems like an easter egg, rather than a user-hostile plea for attention.

I don't think it's really hostile at all. It's probably relevant to almost every visitor and so much better than a modal.

The shaking only supposed to happen when you leave the window. (Like a reminder to subscribe before you close the window)

But I understand why it might be bothering the users. I can remove the shaking if it's too aggressive.
