Paper Soul

Finalist for Pixar’s RenderMan Art Challenge 2026 Diorama Drama; see this repo for project details.

My entry started from a dream: drifting like a piece of paper during a restless sleep. As a first-time RenderMan user, I worked with Claude Code, an AI coding agent, to script the whole Blender and RenderMan pipeline: converting the challenge assets, building the layout, writing the OSL shader that fractures the newspaper, and packaging the scene for cloud XPU rendering. I focused on the story, composition, and art direction. Feedback from the RenderMan team on Discord shaped the final image, from the old woman’s drooping pose to the black background and image format, and the cloud rendering let me finish in XPU on a laptop that couldn’t run it natively.

Features vs. a product

Filed under: Real — liyiwei @ 6:03 pm

A feature set lists what the system can do. Every item is reasonable. But a list doesn’t say who would use it, for what, or why they’d pick it over what they use today. It also can’t tell you what to cut.

A product is a promise to a specific person about a specific job.

[Snippet generated by Claude Code today, which I found insightful for sharing. I plan to expand this post later with more prototype-specific details upon completion.]

AI-generated content consumption

Nowadays AI can generate very high-quality content across documents, code, images, audios, videos, 3D models, and games (which basically incorporate every medium). However, the consumption of such content is still limited by human attention and time. We might want to use AI summarization for work-related content, but not for leisure content for which direct consumption is the whole point. (OK sometimes I watch highlights without watching a game, but only if I missed it live and wished to catch up on the key moments.)

Thus, human creativity remains the deciding factor in which content will be consumed, and AI is just a tool to help produce it, in higher efficiency and (hopefully) higher quality as well. Given the homogeneity of AI-generated content, human generated content, despite being less “perfect”, may still be more unique and less appalling to human consumers.

Accidental stimulant

Last night, after leaving the hackathon, I started to feel as though time was moving more slowly than usual, and my brain felt strangely agitated. The sensation intensified toward bedtime, and I ended up unable to fall asleep at all. After investigating, I realized that several cans of “sparkling water” I had consumed during the event actually contained a large amount of vitamins and stimulants, including caffeine and green tea extract. In effect, they were closer to Red Bull or Monster energy drinks than to ordinary sparkling water. I should have paid more attention to the nutrition labels, but I was too preoccupied with the hackathon to do so.

MongoDB hackathon

This hackathon drew a much larger crowd than the previous one I attended, with hundreds of participants and 93 projects submitted in total. Unlike the previous event, the judging emphasized topic impact and live presentation more than technical execution. Since the theme focused on harnesses and databases rather than motion and graphics and I also ran into hardware issues during my presentation (screen sharing and a broken mouse), I did not perform as well as last time. Even so, the project ranked 10th out of 93, was completed well ahead of schedule (with most of the time spent on demo production rather than on the actual development), and I had a great time on Sunday in a wonderful venue with nice food and drinks.

See this repository for more information about the project, which implements a harness and database backend for my earlier DrawTalk frontend.

Temporary Body by Jerron Herman

Filed under: Real — liyiwei @ 7:30 pm
Tags: ,

In this participatory art project, the artist first invited the audience to create decorative adornments before a solo dance performance among the audience. I enjoyed making a few quick headdresses and immersing myself in the performance. My interpretation is that these adornments and dances act as positive beautifications for the artist, who appears to be gay and struggles to move the left side of his body.

Runway hackathon

For the first time in my life, I participated in a hackathon, hosted by Runway, whose products I have long admired. I especially like their motion brush feature, though it seems to have disappeared after Gen-2.

For this hackathon, I wanted to revive the motion brush as a direct manipulation tool that could complement other input modalities such as text prompts, keyframe images, and guide videos. See this repository for more information, including code, process, and demo videos.

Overall, I found this to be a very satisfying experience: an intense 6-hour event in which I could fully focus on ideation, design, implementation, experimentation, and demo production. Initially, I thought I would be the only participant over the age of 20, but the demographic turned out to be more diverse than I expected. I also got to see some very interesting demos from other participants.

Hand-building

Hand-building seems more forgiving than throwing, as we can add and remove pieces of clay to the model gradually.

Kusama: Infinity

I watched this documentary on hoopla about Yayoi Kusama’s life and art. It chronicles her difficult childhood, struggles with mental illness, and her resilient journey from decades of isolation and obscurity to eventual acclaim and influence on the art world.
The documentary is visually compelling and deeply inspiring. I highly recommend it to anyone interested in art, psychology, and the power of perseverance.
