My college, Gonville & Caius, runs a series of annual competitions for Year 12 students in UK schools, and this year’s linguistics competition challenges students to come up with a language based around Lego! As the competition announcement says,
The term ‘language’ can refer to any coherent systematic communication system. Most of the time we encounter language that is spoken or expressed in writing; but language may also be expressed using other mediums — examples would include sign language and Braille. This year the Caius Linguistics Challenge will be to develop a communication system using Lego bricks (or similar) where the meaning of the language will be encoded in how the bricks are connected together.
