Neat. I'm thinking of making a custom aluminum shift knob, having it anodized, then having it etched so the lettering is silver while the knob is colored.
How are you planning on shaping it? I want to do one metal. I got an STD knob for free when I bought this one (the two knobs, energy suspension bushing and gel for 8 shipped), and I'm planning on chopping it up for a wooden knob later.
