Interesting. I have copied your note and sent it to my daughter-in-law. She and my two grandsons work for ACE Pyro in Manchester, Mich.
Check out the website, designed by my daugher-in-law and check out Starfire controllers, hand built by my grandsons. Also much of the advertising video on youtube was filmed and put together by my grandsons.
