#RippleEffect features Keelin Garcia collaborating with veteran rockers Jimmy Buffett, David Crosby, Bill Kreutzmann, and David Hidalgo on a version of the band's song Ripple, with an accompanying video.
The project was launched on Saturday (01Aug15) to mark the late rocker's birthday.
Fans from around the world have been invited to create a visual 'ripple effect' and they share stories of kindness and gratitude via social media in an attempt to promote children's music education programs.
The celebration of the rock star's life also marks the 20th anniversary of his death from a heart attack aged 53 on 9 August, 1995.
In addition to the social media art project, Garcia's paintings will also be going on show in a travelling exhibition in the coming months.
