Ian B. Jacobs: The cube and cube+'Semantic Web' can be distributed freely. They can be used for derivative works (including used with other imagery and modifications to the cube colors) without permission as long as: The cube shape is not changed; There is attribution of W3C (following some guidelines that we still need to draft).

Questions:

• To what degree of precision must the cube shape be retained?
• Given that this logo is itself a shape, if the shape is changed, must permission still be obtained?  Does that mean that every cube-like image must be approved by the W3C?
