Yeah, this picture isn't great, and you have to view the largest size picture to remotely see it. I was given this neat thing called a Sky Writer that draws prims in the air. You can do some neat things with it, but unfortunately those lines are not temporary prims, and each piece of the line is 2 prims, so it takes up a sim's prim count in a hurry. At least the prims are set to self-destruct after a certain amount of time.
Anyway, I flew around a sandbox while drawing, and somehow managed to draw this red outline of an angel-looking thing.
