Every pomegranate is composed of exactly 840 seeds. To extract every last sweet morsel, you could either spend a half hour picking at the husk with crimson-stained fingers or just knock them clean out of their skin with the ART.
The Arils Removal Tool (ART) from the Shoham company comprises a collection cup, grate, and cover. After splitting and de-crowning a pomegranate, you set the half on a grate that sits over the collection bowl, cover it, and rap the top soundly with a heavy spoon. This knocks the arils (the seed itself and the red, fleshy sac it sits in) free of the pith, allowing them to pass through the grate to the collection cup. The ART retails for $16 on EBay.
