PingPongNinja was developed and designed by James Dennes, and Dave Martin out of Sydney Australia, who both work on Campaign Monitor.
The Campaign Monitor crew take their ping pong seriously and have had an internal ping pong ranking app for some time.
James and Dave one day thought to themselves, "Hey, a lot of other companies would probably enjoy this!" So they created a new version of their ping pong ranking app for use by anyone - PingPongNinja!
PingPongNinja is powered by Django on Google App Engine.
