A power hour is a (drinking) game. During each 60-second round, a song is played. A change in music marks each new round.
I enjoy implementing power hour apps as a way to learn a language or a design pattern because the game is simple and well-specified.
All of my implementations of a power hour app play music from some source via an audio backend with some form of a UI. I aspire to structure the apps with MVC and message passing, with the audio backend working off the main thread.
|ActionScript||PHP search backend with GData API||YouTube embed||Flex + SWF|
|Ruby||Windows Media Player/iTunes||WIN32OLE||wxWidgets|
|Ruby||Local directory of MP3s||Audite||Curses|
|Rust||Local directory of MP3s||Local via rodio/Chromecast||Cocoa/Web view/CLI|
The JS implementation and the PHP search backend are lost to the sands of time.
