LAST week saw the unveiling of designs for Glasgow's pounds 7m John Logie Baird centre, named after the Glasgow-educated inventor of television. As well as celebrating Baird's work, it will display current and future electronic visual science and technology. Designed as a 24-hour 'living' building, with a roof that changes colour with the temperature, it aims to complete the western edge of the city's cathedral precinct. The local architect Andrew Merrylees, who won the competition to design the centre, has split the proposed building into four main public areas. One, the 'Crystal Cranium' will 'take visitors inside Baird's mind' by means of a 360-degree multi-media show.
