OpenCandy and Tux Paint
Between June 2011 and October 2013, the Windows installer for Tux Paint utilized OpenCandy to provide a recommendation for other software you might be interested in. This recommendation occured during the Tux Paint installation process, and did not affect Tux Paint itself. Users who installed recommended software earned Bill Kendrick, lead developer of the Tux Paint, project some residual income. As of October 2013 we are no longer promoting the OpenCandy version of Tux Paint, and have removed it from the Windows download page. (A non-OpenCandy version was always made available, as an alternative.)
Did you know? Adults enjoy Tux Paint, too!
