Shoaib Ali It's bloggin time

While I was reading up on this interesting topic of Thermochromism http://en.wikipedia.org/wiki/Thermochromism. I ran in to some cool projects. These are quite old technologies but yet new to me. Thought I might share.

I can see how this can be so useful for law enforcement agencies and traffic wardens or business to promote their product.

The next technology is heat sensitive fabric that changes color. Also known as Hypercolor t-shirts. These are commercially available and surprisingly enough quite cheap too. I am planning to buy one :D
