I once suggested generalizing radial gradients to also allow conical 
and/or "spiral" gradients. Essentially the idea is that radial gradients 
give you the radius part of polar coordinates, while conical gradients 
are essentially based on the angle part. A scheme that combines the two 
would allow for a kind of spiral gradient.

In terms of simulating them, apart from using meshes, there are also 
some filter techniques that can be used to get a decent (but not great) 
approximation:
