Hobby Projects

NHK Scraper

A quick script to download NHK 高校講座 series of video lectures and re-encode them for iPad. The source files are all in WMV format, so this script re-encodes them with VLC. It also keeps track of which files have been downloaded and re-encoded with ActiveRecord and SQLite.

MD5 Viewer (Note this is unrelated to MD5 cryptographic hashes)

This is a program that I wrote for an Advanced Graphics class. It loads in an MD5 model file and displays it. It includes shaders and animation.

Asteroids Clone

A pure javascript clone of Asteroids. It uses the canvas tag for all rendering.
