Animating Radar Screen

When dorks like me start experimenting with effects and expressions… they come up with something like this.

It starts innocent enough. “How can I use the Polar Coordinates effect to make a radar sweep?”. Then, I start drawing in Illustrator to add some elements. Then I add some text elements using expressions. At this point, I am fully qualified as a nerd as I keep tweaking, adding waveforms, even text that uses trig functions.

What we end up with is a looping RADAR screen. I’ve also added some mysterious object approaching with a tracker object attached and some misc. text driven by X position. and its visibility coming and going with the sweep.
