Ripple was a non-profit click-to-donate internet site and search engine which passed 100% of its revenue to other charities.

[citation needed] The co-founders of Ripple were Jehan Ratnatunga, Matthew Tilleard, Mack Nevill and Simon Griffiths, a graduate from Melbourne University.

A user could click to choose a preferred form of charity, bringing up an advertisement from a sponsor.

Users were able to add applets that function in the same way as the Ripple web site to their profiles and display how philanthropic they are via a 'contributions' count.

[2] Although the affiliate marketing and search interface techniques are not new, donating all proceeds to charity is rare, according to Lia Timson writing in The Age.
