Agreed, I loved my biology courses and lab work and had always had a similar sense of wonder about it all. It's interesting, I'm not sure that came from any teacher in particular and I bet there are plenty of people who just never feel it no matter how you teach the subject. That said, those are beautiful illustrations referenced in the article and they have a ton of teaching value, and I think a lot of core concepts that went over my head would have been way more accessible using tools like that.
