I'm not sure is this correct topic for this. The idea has been grown in my mind to make a challenge/jam where the people release intros or demos, anything goes basically. Intro/demo is basically a compilation of different kind of "effects" and chained "events" which you like to show to the audience, just to show what kind of stuff you can create with GameMaker. Usually the product has also some kind of scrolling and waving text for random thoughts and greetings, and a music track. I know here on forums are many people who know much of about GML and it's tricks, maybe some of these like to show skills on an intro/demo?
