Good evening, I am John Conway, and I make art of very old things, and of new things I have made up. I have a podcast about animals with Darren Naish, and have written and illustated two books with Darren and C.M. Kosemen. My art is funded by people like you through Patreon.

The Darkness

What's in the darkness? A different thing every time you visit (within limits*).

The Darkness takes a painting and reveals it in a way similar to film, the lighter parts are more likely to spark a lightup pixel. This builds over time, both in the canvas and in your perception, until you can see in the dark.

Branch Space

(... is probably not best viewed on a phone)

Branch Space is a little graphical program of mine that aims to capture certain aspects of evolution. It starts with single branch in the middle, growing in a random direction. At a randomised branch length, it splits, and new branches radiate in random directions. This loop is repeated forever. Branches are terminated if the number of branches is too high. Branches run a higher risk of being terminated if they cross another branch. The colour of branches drifts randomly. Random pixels of the canvas are erased over time, making older branches fade.

I like to think of it as organisms exploring ecological space - if they radiate into a space that is full, they run a higher risk of extinction, if they radiate into empty space they can expand and diversify.

Khaan mckennai

Khaan was a small birdy dinosaur that lived in Mongolia, about 75 million years ago. It's found some nice juniper berries to munch on.

Rapetosaurus krausei

Rapetosaurus in a Madagascan forest, 70 million years ago. Rapetosaurus was an unfortunately-named, modest sized sauropod.

The style and composiontion of this painting was inspired by Bill Mudron's 'The Forest Spirit', and you should go and look at his work.

Plateosaurus Portrait

Plateosaurus engelhardti was a large(ish - okay, big cow-sized) sauropodomorph from the Triassic of Europe. I painted it with a big tongue for grabbing things, like these giant horsetails.

Barosaurus, Diplodocus, and Dryosaurus

Barosaurus stands among some puny Diplodocus while some tinsey Dryosaurus walk by, about 145 million years ago in North America.

Barosaurus has generally been thought to be a moderately large sauropod, roughly the size of the many famous Diplodocus mounted casts you can see the world over. However Mike Taylor and Matt Wedel (of SV-pow! fame) argue that some truly enormous neck vertebra belong to Barosaurus giving it a neck seventeen metres long, and making Barosaurus a horrifyingly colosssal gargantuan thumping great mountain of a beast. It is also an exceptionally beautiful sauropod.

I used Scott Hartman's skeletals for reference.
