| Free, legal art for open source game projects.|
Open Game Art is a media repository intended for use with free software game projects.
Its purpose is to allow developers to easily replace programmer art with high-quality, appropriately licensed artwork. It accepts both 2D and 3D art, as well as sound effects and music, unlike similar projects such as ccMixter, which only deals with audio samples and songs, and The Freesound Project, which limits itself solely to samples.
All content found on Open Game Art is licensed under free licenses, with varying copyleft status. The acceptable licenses currently include the GNU General Public License and LGPL versions 2 and 3, as well as numerous Creative Commons licenses including CC-Attribution 3.0, CC-Attribution-ShareAlike 3.0 and CC0. The latter is functionally equivalent to releasing content into the public domain, relinquishing as many rights as possible.
Content under highly permissive licenses such as the WTFPL or public domain-like licenses, while not explicitly allowed, is able to be readily relicensed as CC0, and as such can be uploaded to Open Game Art.
The project does not accept content licensed with non-commercial clauses, as these are perceived to restrict users, thus making the content non-free.
Being a repository for free content, much of the site's content is created using free software such as GIMP, Inkscape, and in particular, Blender.
Artists from the Warzone 2100, The Battle for Wesnoth and the recently released Frogatto projects, amongst others, have contributed assets.
The site also has a section for articles and tutorials, as well as a discussion forum for its users.
Hosting costs are currently paid for by the site operator. Donations are accepted through a PayPal account, and are used entirely to commission new artwork, with users being able to make requests as to what kind of artwork is commissioned.
From June to July 2009, a pixel art contest was run to create clothes, hair and accessories for a pair of humanoid sprites that had been commissioned exclusively for Open Game Art.
To stimulate new artistic contributions, the site also hosts an informal weekly competition called the Friday Challenge, wherein an artistic theme will be announced on a Friday, and entries will be voted on until a winner is decided nine days later.
