IMHO you should credit the author of that video. While your work is amazing and you should be praised for your achievement, you should also make it clear about your inspiration.

Awesome job, I'll install it as soon as it hits the App Store

very much agree. apart from anything else, the inspiration is so obvious that if you don't credit you're basically just asking for a fight. and if you get it in the app store he might even be in a position to hit you with a DMCA takedown. my guess is it wouldn't happen, but why take the chance when all you have to do is give credit where credit's due? it's the right thing to do anyway.

I emailed Daniel Hooper (the originator of the idea) about this when I did my own version and here's what he said:

"I'm glad to see others like yourself implement my idea, and it would be great if you could give me credit when you release your app."

I think giving him credit is the right thing to do. It costs nothing and is more than a fair deal given how brilliant a concept it is.
