Let me be honest here: I know very little about Knot Theory. I'm sorry.
I've a friend though, someone with no training in Mathematics at all but who is a huge fan of knots (for whatever reason), who knows even less than I do about it, apparently. Thus I'd like a book or something as a gift we'd both enjoy: an illustrated classification of knots up to some large order, say, like this:

Do you have any ideas? They don't have to be books.
Please help :)
