Go without the grid
Hey 👋 — today's mix has a nice throughline: games that quietly rewrite their own rules, followed by a couple of things that remind you why the rules exist in the first place. Leading off, someone took Go and threw out the grid entirely.
Show HN: Voronoi Go
Go's square grid is basically load-bearing — it's how you count liberties, how territory gets carved up, how the whole game clicks. This browser build swaps that grid for a procedurally generated Voronoi diagram, so every board is a different tangle of irregular cells and every game forces you to re-learn spatial intuition you didn't know you'd memorized. It's a small change with big downstream effects, which is exactly the kind of tweak worth playing with (via HN discussion).
The Power of Two – Game that turns choices into a soundtrack
Sticking with games that bend their own mechanics: this procedurally generated piece by VOLNA has you crossing a desert in a futuristic vehicle, and the only input is a single binary choice, left or right. That choice steers the terrain, reshapes the music in real time, and slowly builds a personal song out of your path — turning a minimal decision into the whole aesthetic engine of the experience (via CreativeApplications).
Goodgrowth: boot sequences, spinning discs, and the art of the portfolio
A Codrops case study on a personal portfolio that opens like a PlayStation or Dreamcast boot screen — spinning discs, chunky console fonts, all built with Three.js, GSAP and Cinema4D assets. It's a good reminder that a portfolio site is itself a creative-coding project, not just a shelf for one (via Codrops).
Breaking Claude Code Opus 5 auto mode
Security researcher Johann Rehberger found a prompt-injection attack that beats Claude Code's Auto Mode about 80% of the time, tricking it into extracting and running a malicious file from a zip archive. In some runs, Auto Mode actually blocked Claude's own attempt to kill the malware process it had just launched — which is a fairly vivid illustration of what happens when an agent's helpfulness outruns its judgment (via Simon Willison).
What happens when a GPU reads memory
A properly obsessive reverse-engineering post: the author traces a single GPU load instruction on an RTX 4090 through L1 cache, address translation, L2 slices, and out to DRAM, using timing experiments to map behavior Nvidia never documented. Dense, but the kind of dense that pays off (via Lobsters discussion).
