Thanks for the feedback! I settled on the current speed after showing it to my friends, but it seems like your computer is rendering it in a different framerate leading to the jitter. Do you know of a way I can increase the CSS animation framerate without changing the speed? Otherwise I'll just reduce the speed to reduce jitter.

I have autocomplete on my to-do list for features but decided to just ship it before the scope of the project got out of hand. Thanks for the suggestion.
