This is what I have done in the last few years. Web projects are done mainly in the last year.

• News mining and publishing service
  
  PHP- and mySQL-based system downloads two levels of news articles (short description and full article) from special RSS channels. Filter functions fix text and HTML code, remove all similar news (by several criterias, such as text and titles similarity, links similarity, image similarity). System downloads all needed image files for news. Sorting functions assign news to categories and publish them into DLE-engine based domains. Depending on category and content, news may be published immediately, or under "pending moderation" flag. There are also admin panels to set inclusions, exceptions, replacements and stopwords for articles.
  
  System has: advanced statistics; multi-user interface - each user group can operate own channels and publishing domains; news may be sorted by language; advanced moderation admin panels; advertising campaign settings page.
  
  System is linked with cnstats, allsubmitter scripts with own backlink checking functions, openads.
  
  Some features: downloading and filtering over 2000 articles from over 200 domains daily; 35 mySQL tables and near 500KB of optimized PHP code; may be run on FreeBSD or Linux.
  
  Check out these domains for result: allebook.org, allhumor.org, allprogram.org, coolmusicvideo.org, favdesign.org, games-mania.org, mobika.org, music-mania.org, myfunnymovie.org, photosmania.org, videotop.org; (warning, 18+ content) anigame.org, allsexvideos.org, sexphotomania.org.
  
  
• Google results parsing script
  
  As you probably know, Google engine does not show more than 1000 results for one query and also does not allow to read them faster than once in a while. My script is able to read all available results in a short time. PHP with sockets used to read results, and I store data in mySQL table for further operations.

• Remote statistics reading system
  
  PHP based system to download special statistics from many remote accounts simultaneously, such as cj.com, amazon.com and other sites and traffic selling engines. For example, it may download $, sells, clicks data each hour, and save them on your server. Then system may produce graphs for each stored parameter. System uses mySQL to store data and JPGraph lib to produce graphs. If remote account needs to input captcha for every login, system downloads it and shows to moderator for input.
  
  Actually this script may be used to login into any remote system and read any template-based data.

• 2D real time strategy game engine
  
  It is not finished project. Game uses map with square tiles. Units may be selected into groups. The best thing in the engine is group pathfinding algorythms (A* with heuristics). Select some units and order them to go somewhere :)
