Peter McKinstry: "There was no grand plan in designing the Lazlabs logo. BBC Graphics provided it for episode 6, and I thought it looked a bit too Gallifreyan. But when it came to designing the ring, using the Lazlabs logo, with additional Gallifreyan etching on top, tied in nicely. Within minutes of it being shown fleetingly in the trailer for the series' second half, people were already discussing it on the net!"
