    Some thoughts relating to the gradual but very apparent normalisation of genAI image use in the public display sector:
    An unfortunate reality for those of us creating art for the public display sector is that third parties hired by the same clients we initially produced the art for may run our work through some level of genAI slop machine, even if we try everything in our power to prevent it.

I have friends that this has happened to in circumstances that were completely beyond their control, yet have still received the brunt of the response, with the actual guilty parties remaining anonymous, and the lack of due diligence on the client's part remaining uncriticised.

So, given I'm stepping further into the public display sector, I want to make something very clear now:

If you ever see my work modified by genAI or mixed up alongside it, I was not the party who used it, I did not approve it, and if in my power, I will certainly fight against it.

    Was just doing a quick test to make sure the mouth could close, and accidentally created a monster.

    A message to fellow scientists - please do not under any circumstance use generative AI images as "illustrations" to promote research. The relationship between scientists & artists is historically long standing and mutually beneficial. Don't set a precedence by trampling on it.

    Here's a look at a cool thing I've been working on for @arvalis. Lizard anatomy is well studied/figured, but many of the resources are hidden in literature that may be unknown/inaccessible to artists. The mission was to make an idealised, artist-friendly ref for lizard muscles.๐ŸฆŽ

    Introducing a crazy new look for Spicomellus, based on newly described osteoderms unlike anything we've ever seen before. I was brought in to produce a life reconstruction based on the new material, published today by Maidment et al. in Nature: nature.com/articles/s4158โ€ฆ

    There was a time when Jurassic Park movies put genuine care and effort into the scientific minutiae. Just saying.

    While we can ensure its structural integrity, employees are still reminded not to walk *too* close to the glass.

    My first PhD paper is out in ProcB! royalsocietypublishing.org/doi/full/10.10โ€ฆ I'm excited that this whopper of a first chapter made it to the finish line, and I'm really proud of what we've done. I may post a more detailed breakdown of interesting findings later, but a quick summary below:
