Videos from physics springs system
The model in the movies/pictures is actually a minigun made by sentral on these boards (he's making models for the game). The lines coming down is where the thrusters make contact with the ground.
People have had problems with the movies ( had to download fraps just to watch the .avi files), and I've also noticed that downloading from this host was running a tab bit slow (perhaps I should post on rapidshare?)
I'm in the process of taking some screenshots and perhaps trying to find a better way to record video.
Each of these files is about 20MB, so unless you have broadband don't bother (these are less than 30 seconds apiece, on lowest quality and only 25 fps).
Here's some footage I recorded using fraps, it just shows the latest thing I've implemented in my physics: a set of thrusters that stabalize a hovertank (for the computer game I'm currently working on).
