Doris is a Fully Functional Steampunk Gun by Jonathan Alberico
Doris is one of two functional steampunk guns which, unlike most steampunk art, actually do what he intended them to: they fire projectiles. His other gun, named Black Betty, can also fire an assortment of fun objects.
Implications - Doris is a stunning air cannon with the ability to fire bouncy balls with enough velocity to rip through boxes, bounce back, and drill the videographer in the hip -- now that's power. Jonahtan Alberico is a master of his domain, and it won't be surprise to see corporations and the art world take note of his skillset.
