Honorable Discharge Series

Each of these pieces appear at first to be some kind of grenade launcher.

 Upon closer inspection one finds that pulling the trigger flings the safety lever away, leaving the user with a firmly attached, active grenade (dummy practice grenades were used for these pieces, not real ones).

Every element was found — scrap yards, second-hand stores, dumpsters — then cleaned, stripped, sorted and rebuilt. Found aluminum is TIG-welded and sanded seamless; nothing is cast. The electronics are salvaged from consumer devices, repaired and rewired so the piece does something when you touch it.
