Algodoo

Draws an outline around objects that are placed within the large circle area. Make sure objects are glued to the background so that they don't float around, and they also should have collision layer A (or 1) set.

The laser scans objects in a circular pattern. Press Alt key to clear the generated outlines.

Play around with this to see what interesting patterns you can make, or if you can figure out any good use for this.

Also take a look at my Linear Outliner scene.

Thanks!
