Possible to revert back to original state?

[nvirm]

Hi! This is an awesome project! I was wondering if it is possible to revert back to the original state once glitched?

Idea: Load website with a header image -> glitch it after 1 second, then after x seconds glitch fade/just return to original state.

Or

Would the right way to approach this be by having two divs placed on top of each other, bottom one with the header image, and glitchresult at the top div?
