Requires Unity 4.3.3 or higher.
This script uses Unity's line drawing functionality to create an ever changing circuit board like animation that can be inserted into your scene in any way you like. Each line appears, runs around until it gets blocked, and then fades away making room for a new line.
This can be very useful for creating your own custom and royalty free circuit board images, or for adding an interesting effect to key surfaces on your game.
The main part of this asset is a single script with no external dependencies. If you want it to do something slightly different and you feel comfortable working in C# then feel free to modify it to suit your application.
