Dos Equis Blowdarts Game
This was my favorite of the simple games we built for Dos Equis a few years back. It's written in Actionscript 2.0, using the GetMicrophone() function to analyze audio input and trigger blow events.
You blow into your computer's microphone and the dart shoots. Fun to play, fun to build.
Around the same time, Stephen Petronis and I used the microphone event triggering to build Mr. Anxiety. It's a fun one to play with a group. (Playing alone in an office environment is sure to draw some interesting looks.) Enjoy!
