Today we had tons of fun at the Over The Air conference. We went with Caz and met up with our friend Mr Duck who brought Alistair along too. There was a nice man called Terence who let us play with his 3D printing machine. Leo found a cool new seat which fitted him perfectly. Mr Duck got a new hat. And we found some friendly faces to play with – Kitty and Darth. We also had a tour of The National Museum of Computing where we saw lots of ancient dusty hardware which Caz and Alistair used to play with when they were little.
