php edna is a port of the edna MP3 server to PHP, but with its own features. The most noticeable difference compared to the original edna is the XHTML 1.1 Strict compliant output with UTF-8 charset and support for custom themes via CSS. There are also a few other goodies like enqueue links and tarball generation.
Concede is a computer version of the board game "Take It Easy". The game is a kind of mix between 4-in-a-row and bingo (a.k.a. lotto). The player starts with an empty board where 19 hexagonal tiles have to be placed. At each turn, a random tile is drawn and the player must put it somewhere on the board. Each tile is marked with 3 numbers (from 1 to 9) and the player must try to make as many complete rows as possible with the tiles he gets. The problem is that there are more tiles in the game than places on the board, and they come in random order.
