I recently launched Code Maven from Crunchzilla. It helps teens learn a little about what they can do if they learn more about programming.
Code Maven is a curious blend of a game and a tutorial. Like a tutorial, it's step-by-step, and there's not-too-big, not-too-small challenges at each step. Like a game, it's fun, addictive, and experimentation can yield exciting (and often very cool) results. I hope you and your friends like it. Please try Code Maven, tell your friends about it, and, if you have suggestions or feedback, please e-mail me at email@example.com
Code Maven builds on Code Monster. Code Monster is for kids ages 9-14 (but many even younger have enjoyed it too, especially with a little help). Code Maven is for teens ages 13-18 (and curious adults too, especially adults who have never programmed before). Because Code Maven is built for older kids, it assumes a longer attention span, and so is a bit harder, has more explanation, and has some additional fun projects. Pick which one you like based on the age of your kids and your interest. You can try them both at crunchzilla.com!
