Thermochromic book cover animation worked on with Henry Hobson. Fluid animation through thermochromic (colour-changing with temperature) ink and a grid of heaters produces an effect unachievable any other way. This was nominated for the Conran Design Award but sadly missed out.

Henry and I met via email whilst I was studying at Imperial College. He had the thermochromic book idea and several experiments under his belt - largely with nichrome wire (you try soldering to it) and carbon based inks. I designed the PCB and control system and built everything up. We went with thick-film carbon resistors for heating elements in the end. The system ran on a PIC16F87 and I wrote the whole damned thing in assembler. Looking back I still resent Microchip for the need to BANKSEL.
