I've been wanting to do this for a long time, really!

Consider this (can your code handle this?):

#declare Blob1 =
blob {
threshold .3
sphere {<0, 0, 0>, 1, 1}
pigment {color White}
}

#declare Blob2 =
blob {
threshold .3
sphere {<0, 0, -1>, 1, 1}
pigment {color Blue}
}

blob {
blob {Blob1 translate 1*clock*y}
blob {Blob2 rotate 30*clock*y}
}

Now imagine if you built a bunch of parts for a human using blobs and declared
each one, then incorporated each part into another one.  You could move the
parts to make the character walk and talk ect.  Considering that making, for
example, an arm with blobs can take 30 or more components, having to tranform
each one individually is a real pain.  With this syntax, each blob would be
just like any other primitive, yet they could interact with other blobs, which
would be cool.

I think it'll be great.  Glad to hear that Chris Young likes the idea.:)
