I built a tool to visualize the Peter Thiel stock portfolio (13F data)
I've always found raw SEC filings painful to parse, so I built a site to make institutional holding data more accessible and visual. I recently updated the data to analyze the peter thiel stock portfolio (tracking Founders Fund and associated vehicles) for Q3 2025. It's interesting to see the divergence from standard tech indices—heavy on defense/hard tech and very little consumer SaaS. You can see the visualization here: https://www.13radar.com/guru/peter-thiel Would love any feedback on the UI or suggestions on other metrics I should calculate from the 13F data.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
