Check out some great, brand new net art by noted digital artists including Shu Lea Cheang, Netomat's Maciej Wisniewski, and Rhizome's own Mark Tribe -- and do some good at the same time -- if you log on to "Shine." It's a benefit for Amnesty International, and this online exhibition of special commissions of web-based art by 12 hot artists also celebrates the 40th anniversary of the human rights advocacy organization. All the work relates to the theme of "light," as in the candle flame that serves as Amnesty International's logo. Links are also included so you can easily join an Amnesty International email campaign.
