Hi, I’m the guy who wrote the code. Here’s a gist for you: https://gist.github.com/porada/5047435

That is awesome! I'll definitely absolutely butcher that code once I get some spare time :D

It looks incredibly cool when rubber band scrolling kicks in. Well done!

Off-topic of the off-topic but can you explain to me what's cool about it? I'm not a web developer so all I see is that the image doesn't scroll off but appears to shrink. Genuinely (not a troll), can't think why that's useful though ...

I don't think it's useful in a technical sense, but it did catch my eye so much that I scrolled up and down a few times to watch it. Take that and stick it on a client demo and you might help secure another sale.
