Ha, very nifty! I saw the Gobstopper advertised a while back along with a new range of Colin McRae stuff (I think RCM wer advertising it on Facebook as well?), but the image of it looked a bit cack. That looks really good though!
If only I could have the real Gobstopper for £20...
EDIT: If its on the site...
