Nice, I like the work you done. The beam that you added with the cows moving up when you're abducting them is so cool. The shield effect is pretty cool too.
To make the nodes I did do it in blender, I used a flat plane roughly the size of the pentagon faces and used the magnetic tool (not sure what it's actually called) to place each node individually. The snapping magnetic tool automatically rotated it so it faced the right way. I'm sure they're was better ways to do it but I didn't have time to figure it out.
