In the 90s, clothing that responded to temperature was the 'new thing'. It's not seen so much now, and it's kinda not the best, the dyes end up washing out, wearing out, and the colours end up sticking - but I remember when it was introduced with a colour changing tomato on the front of the 'red nose day' t-shirt in the UK and thought it was cool, or there were full t-shirts where they'd change colours in a mixture of sunlight and frankly how warm you were.
I look forward to cloth and electronics being more responsive and integrated together, and I look forward to them serving a purpose, as well as looking cool:
I should really do something with the conductive thread I have...
