The next phase of my development was a game changer in my opinion. I had been focusing on research into touch and user interaction, when I discovered Thermochromic ink. I had never heard of this before, but soon realised that this was already incorporated in various drink cans. The ink itself is affected by heat, so by touching the surface, it would cause the ink to disappear. I was fascinated by how this process worked and quickly began creating quick experiments. The GIFS below show examples of this and although I haven't used my hand to change the designs, the process is pretty evident.
