This is true. A bookmarklet would be nice. But, I am not pinterest (who distributes a bookmarklet) or david walsh or anybody that gets tons of traffic so a bookmarklet that I distributed myself would just get lost in the mix... and that wouldn't help anybody.

I also wanted something that had some UI and a little control (ie. the ability to change the timing).

It's not perfect. I know. And you're right... People who know nothing about code, also know nothing about iframes, so there's that.

I'll have to come up with a solution for the iframe issue down the line. Maybe I'll distribute a bookmarklet on this site? =)
