Heat activated color changing paint

This heat activated color changing paint looks like it would be a lot of fun for projects, a tub/shower that changes color based on temperature is awesome – “Eclipse is a single event heat reactive basecoat that changes from Black to White or from Blue to White. Eclipse can be sprayed through any standard paint equipment. For the most brilliant white change, Eclipse should be applied over a white base. For unlimited possibilities try putting a Candy Concentrate over the Eclipse.” [via] – Link.
