Linden Lab, the creator of Second Life, has acquired graphics technology from Windward Mark Interactive. Specifically, Linden Lab will own two WindWard Mark products: 3D graphics technology WindLight and Nimble, a realistic 3D cloud simulator. The acquisition, terms of which were not disclosed, also gives Linden Lab the 3D associated intellectual property and interests. After the transaction closes, Linden Lab will open source Windward Mark’s graphics technology and integrate it into the Second Life Viewer software. The five founders of San Francisco Windward Mark’s will also join Linden Lab’s new office in Boston. Release
