Of course these aren't as good as Ironhide's ones... I am just 17 years old and I am a beginner :]
Still I want to share a game I coded in an engine called 'GameMaker', which is a remake (and improved) version of the German game 'Achtung die kurve!' (watch out for the curve) with lots of new options to enhance the gameplay experience.
Achtung die Kurve is a simple snake-like game that's yet very fun to play with friends. There are enough games that you can play with 2, 3 or 4 people on one keyboard, but this one lets you play with up to 8 people =)
Every player controls an ever-growing line and must prevent their line from hitting any other line or the outer boundaries, by using a key for turning left and a key for turning right.
Download version 1.3 here: http://dl.dropbox.com/u/43582062/Achtung.exe
And here's some fancy screenshot for you:

(note: these are uncontrolled and therefor straight lines in a round which just started)
