I made a few modifications to lololoer's Radar simulation scene just to show him a few ways that it can be improved. I changed the following:

1. I changed the laser "maxRays" from 1000 to 1. That had the biggest effect by reducing all of the reflections that caused the radar beam to look random instead of rotating smoothly.

2. I slowed down the rotation rate.

3. I changed how the images blank out after a couple of seconds. Originally the density of each image circle would go to zero after a few seconds. A better way is to change the "timeToLive" value from infinity to 3 seconds.

Now the images change normally when the scanned objects get moved.

Hope you like these changes, lololoer, and maybe you will want to use some or all of them!
