You know what, that's actually something I hadn't considered before. There's definitely a bias towards a pelican cycling from left to right on a red bicycle against a blue sky and green grass.

Blue sky and green grass aren't that surprising, but the color and direction are interesting.

When I finally build the proper gallery I'll throw in a few other creature-vehicle combinations, and track some characteristics like which direction, color of bicycle, general pelican geometry etc. It will be interesting to see if other creatures end up with coincidentally similar design choices or if that's unique to the pelican-bicycle combination.

View on HN

In photography (and probably art in general), there's a composition "rule" to frame moving subjects from left to right.

So the direction may not be that interesting!

Is it culture dependent? Is it because in English we read left to right?

There was a glorious moment when I thought that the Chinese models were more likely to produce right-to-left cycling pelicans, but sadly that trend didn't seem to hold up.

Chinese is also written left to right

For almost the last 70 years, Chinese has been left to right.

Before that it was vertical (although the ordering of the columns was right to left).

Arabic or Hebrew would be better tests for that.

I wonder if that changes in countries where the main language is written right to left?

That was my first thought too, I wonder if it works the same in countries speaking arabic (as that's the first one i could think of that's a language with truly no-buts right to left writing).

Arabic native speaker here.

Yes, people will usually post or draw a bicycle right to left which is going to ve opposite of what normally is drawn. I tried the prompt in arabic for many models and I don't recall any adjusting it based on that difference at least culturally speaking.

It is. All over the Arab world, imagery in ads is “backwards” and I believe several companies will flip their ads horizontally, and UI localization involves flipping graphics.

Do the gears and stuff sit on the other side of the bike in the Arab world? Otherwise I'd expect cycling ads to still show a bike going from left to the right, considering https://news.ycombinator.com/item?id=48951828

The other thing to consider (as someone who frequently take a photos of their bike) the common direction has the drive side out! In cycling forums it is sacrilegious to post a photo of your bicycle without showing the drive side.

Beat me to it - but I had the same thought. Most amateur and nearly all professional studio photographs of a bicycle will have it drive side out so I expect this plays some role in it.

> the common direction has the drive side out

Took some searching and sleuthing to actually figure out what "drive side out" means, as I'm just a casual "from A to B" cyclist: apparently this is referring to the side the chainset, chainwheels and all those things are on.

side scrolling video games were always moving from left to right

Well except for Jungle King

What's interesting is that given the fairly general and short in length prompt for the test, none of the models are attempting things like more discrete details of the bike. Such as showing V-brakes or dual 160mm disc rotors, rear derailleur, water bottle in a bottle cage, panniers, lights, saddlebag, the rider wearing a helmet, or other details that might be found on as vague a description as "a bicycle".

It'd be hard to fully compare, but I think a truly random "creature-vehicle" along side the pelican test would catch who's gaming and who's not.

I'd also enjoy the absurdism of "Herring on a pogostick"

The models are already brilliant at that. My own todo app generates 128x128 pixel art icons for my todo items. They are mind blowingly creative and funny.

There's a bias in the direction all things face. You can ask these models to generate a thing animal, car etc and you will notice that 90% of them will converge towards the same sort of results. If you ask for something rotating, 90% of them will rotate right and a few odd ones will rotate left.

I have done some variation of the other animals, also for something more tricky where they need to calculate things, I ask them to draw an SVG at a certain angle.

For example: "generate an SVG of a chessboard seen from a 45 degree angle slightly higher POV" or "generate an SVG of a basketball court from a TV broadcast perspective".

I find Gemini is still the best at creating SVGs.

The art styling is more or less uniform too.

I haven't seen many AI works that produces a pelican on a bicycle done in a "Ligne Claire" style, for example.

I guess AI's narrows down the output probability space drastically and converge on some agreed upon aesthetics. Works great for computer programs but bad for art.

I thought my joke post was silly and then I read new comments and I'm like, "I didn't try hard enough" lol

Bicycle color, grass color and sky color are all part of the prompt.

>Cartoon illustration of a white pelican wearing a red scarf, riding a red bicycle along a gray road with white dashed lines; the pelican has a large orange beak and webbed orange feet pedaling, with white motion lines behind it; the background shows a light blue sky with white clouds, a yellow sun, two small black birds in flight, and green grass with tiny white flowers in the foreground

That wasn't the prompt. That text was generated by asking the model to describe an image and feeding it a rendering of the SVG it had previously generated.

No, the prompt I always use is "Generate an SVG of a pelican riding a bicycle".
