Forget T-shirt cannons. Interpreting orchestra music via the medium of Tesla coils is the future. Video projections are so 2007.
Imagine these on the lawn at Tanglewood or in the ballpark for a San Francisco Opera performance? What about using them instead of -or in conjuction with- the cannons (which could also launch t-shirts) during the 4th of July 1812 Overture? Miss Mussel’s head just exploded.
