How is this computed?

round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10) — computed 2026-09-03. Adoption (stars, forks) is never an input.

A collection of experiments demonstrating that PDF files can contain JavaScript and interactive behavior, most famously a playable Breakout game inside a PDF that works in Chrome. It serves as a demonstration and educational resource about the surprisingly powerful PDF specification.

Use cases

  • play breakout inside a pdf file
  • learn what javascript can do inside pdf documents
  • demonstrate pdf security risks to a team
  • understand the pdf specification's scripting features
  • find examples of interactive pdf hacks

When to choose

  • you want a concrete, working demo of JavaScript-driven behavior inside PDFs
  • you are researching or teaching about PDF format capabilities and attack surface
  • you want to reproduce the Breakout-in-a-PDF hack

When to avoid

  • you need a production PDF generation or manipulation library
  • you need a maintained tool with a license and ongoing support
  • you need PDF features that work across all readers including Acrobat and Foxit
