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 https://github.com/1iyiwei/drawtalk-runway-hackathon for more information, including what the motion brush is, how it works, and the design and implementation process.
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, with a few other participants appearing to be older than me. I also got to see some very interesting demos from other participants.
