The photo on the front cover had me stumped - all I could come up with was a hybrid Copiapoa Krainziana / Cinerea but the background coast didn't fit in.
I would never have guessed this to be a Melocactus too. But a the background does not seem out of place for a Copiapoa? I know them to be coastal plants, usually on cliffs next to the water taking advantage of the water vapour, for many pictures I can remember having seen of Copiapoas. Still it looks more like an Echinocactus or Parodia to me...

Thanks Teg!
Interesting article Terry. Some of my colleagues in my research group Cardiff University worked on nonphotorealistic rendering - computer algorithms that take in a photo, and automatically re-render it in an "artistic" style.
Below are one or two results from one of my photos; if anyone else wants to try, you can upload your own photos at

Certainly a most interesting divertissement

I couldn't work out what it was when I first saw it either... even though it was me who'd done the layout for Paul's article!

My colleagues did this quite a while before deep learning became fashionable. Indeed Paul Rosin, the main chap, has even co edited a book about it:
Image and Video-Based Artistic Stylisation

But I suspect we are now getting a bit far from C&S...

That Melo is on my wish list now, white spines & white cephaleum, what's not to lust after.
