The video of the stars looks good... One thing I like about the enclosed stars is that they have a very defined light pattern. I think they are going to be an awesome addition to your show.
I am thinking of adding 160 of these to my display all over the show.
How long did it take you to build the 10? Did you use hot glue or an epoxy to seal the pigtails into place?
I am planning on using an epoxy for the pigtail holes. Also I am using double sided tape to mount the pixel to the back. That way it can be removed in case of failure amd heat/cold should not be a problem.
