Osu! Replay Viewer

This Python application renders replays from the osu! rhythm game. I wrote a parser for the replay format that the game uses and then wrote a pygame application to render each of the players' cursors from the replay files that were downloaded. I also created a version that would render to image files instead, so a video can be encoded using FFmpeg instead of needing to screen record. Finally, I uploaded several videos to YouTube, which were viewed thousands of times. My videos also got mentioned on an official blog for the game, and many people are now making similar videos, influenced by my work.
