THE SPICE GUN
FYI: This isn't on the market yet, but I know I'd buy it.
Zhu Fei (China), designer.
There are three chambers in the barrel that can hold your spice of choice--salt, pepper, sugar, hot peppers?

As to how it works: The designer's own words:
spice gun is different from the other casters, it has more fun! when you pull the trigger to compress the air in the air bag. The handspike will push the bottom of the seasoning bottle to make the nozzle in the turntable to retract and spray the seasoning.
