If you have discovered that what is missing from your life is a small, 3D printed piece of plastic with a unique arrangement of disks and squares on it, in a variety of colours, then I have just the thing for you. A Red Nose Day tag.
They are on sale in aid of Red Nose Day from our Departmental Office in Computer Science. They look great on a key-ring or as novelty ear-rings. Every one is unique and we will be using them in the lecture on Friday for some fun and games. They only cost a pound each. Bargain.
And don't forget that you can sponsor me, and maybe get me into that tutu, here.
