Naughty Panther describes Plinkton as an application that lets you “create a rhythmic groove over a bed of smooth ambiance.”
Plinkton is less Kenny G, though, and more ambient Pong.
The app lets you select from three background tracks and 4 “plinkton sounds”. The “plinkton” moves around the screen, triggering sounds as it bounces off the edges of the screen.
Plinkton can also act as an OSC sender, letting you use it to trigger other apps.
Plinkton sells for $.99.
