A quick look at the documentation for the Group node will reveal a variable called blendMode. It is of type BlendMode, which is a Java enumeration. There are 19 different blend modes that range from the obvious to the obscure. It may not look like much, but there is a lot of special effects potential contained in those 19 enums. If you take a black rectangle and blend it with a circle that contains a radial gradient... Presto! Instant spotlight. If you then take this spotlight and blend it with other nodes... Well, cool things start to happen.
