This repository of Phil Kirkland 1970s science textbook illustrations - aka An artist's interpretation of a teenager's head exploding in science class - is an absolutely unbelievable psychedelic undertaking. I've no idea what textbooks look like these days but I know if they contained images anywhere close to this calibre I'd be paying a whole lot of attention.

I'd recommend diving into the rest of images on 50 Watts but, selfishly, I'd rather peruse it myself and keep sharing individual collections. Every set there is capable of blowing your mind in some fashion.
