OK, here's the latest installment of the pimped out clays:

It took several coats of blue dye, as the clay just soaks it up like a sponge. It's a little uneven as the clay didn't absorb it uniformly, but that adds character :) Then I buffed it with carnuba to seal it and give it a little sheen.
And the white tip is heat shrink tubing - seems to adhere nicely, and I can hold it better with my teeth. Haven't smoked anything in it yet.
I also tried dying one red, but that was just ugly. It came out looking like a rather anatomical pink. So I tried overcoating it with yellow to see if it would get orange. It didn't. It just looked mottled. So that one was relegated to the dustbin.
