lol AI always has this dang idea, it's obsessed with making a paper crane fly. Looks nice though! I never let it do it 😂

I told it to make a story about a paper crane though

If you ask Opus or deepseek for ideas for demos and cool things it loves recommending a paper crane for various things.

That is one that's way more common for sure! Also Steam engines, and ship yards 😂

The crane is my favorite so far. Was this one prompt again, or did the journey part need more steps?

This wasn’t one prompt

Makes sense, the journey has a lot more going on. Roughly how many prompts did it take?

Kevin Ngo's profile picture
Kevin Ngo28 days ago

It was like 4 prompts total. Mostly to improve the origami part and the journey scene

Alessandro Moretti's profile picture

Four prompts for that is very little. I'd guess the origami folds took the most tries.

JavaScript did all the drawing, and the crane still stole the show.

Handing it a fold sequence and letting the code work out where the paper lands is why the folds look physical instead of keyframed. Where did the sequence come from: a standard crane diagram you typed in, or did Opus work out the folds itself?

bro, drop a patreon subscription for your workflow/prompts you're using, I see no meaning of 100% not giving a single tutos of how you do your work

this is so good. How long did the whole thing take you?

Did it handle all the canvas math in one shot, or did you have to guide each scene separately?

Kevin Ngo's profile picture
Kevin Ngo28 days ago

no the first cut wasn’t good. Needed a few more prompts to fix things like the origami timing

EDDY VU's profile picture
EDDY VU28 days ago

motion timing is always where it fights you. did you have to break it down into stages?

Opus 5.5 用 JavaScript 一帧一帧画出来的纸鹤动画,这是真的将代码融入细胞了

the paper crane is so cute, every frame in js is crazy

so this is why claude doesn't have image and video model?

the fact that it was drawn frame by frame in javascript is wild. this feels less like ai generating code and more like ai becoming an animator

Was this one long prompt or lots of rounds fixing scenes? Curious how often the crane came out looking wrong.

what about showing the prompt?

Asmir's profile picture

did it hand key the crane's folds as keyframes or actually compute them from the crease geometry?

Kevin Ngo's profile picture
Kevin Ngo28 days ago

It computed them. It's given a paper fold sequence, and the code works out where every piece of paper ends up and which creases it leaves.

The fold-sequence approach you described sounds useful beyond the film. A step-through view that highlights the next crease could turn the same geometry into an origami guide, with time to stop and inspect each fold.
