The Polygons of Another World - realtime interactive rendering in R
summary
Demonstrates that base R reaches interactive frame rates (benchmarks show 30 fps on RStudio/quartz and X11 responding over 500 Hz) by using native raster double-buffering and grid raster to copy frames, driving a pixel engine that scales to 5,000 sprites. Implements event-driven input via grDevices callbacks, ships the nara and eventloop packages, builds an R drum machine that plays and responds in real time, and ports the Another World VM into R with keyboard, animation and synced sound working though a few bugs remain.
