Howdy people!
The first article on how to develop a Tetris® clone is out. In the index, there's other two articles previewed, but they have not been posted yet. They will, soon. You can check the articles here: http://geekswithblogs.com/felipe/articles/38576.aspx
That is the link you can always check to see if there was any update in the articles. Of course, I'll always add a post here in the blog too, as a notice for updates. That's it!
