From Mouna Andraos, some notes on thermochromic inks:
“Basically, the main company in the US seems to be Chromatic Technologies. They have the widest product line and appear to provide some of the smaller resellers as well (they sell minimum by the 1/2 gallon i think). The stuff we have right now is from: Matsui. It’s for screen-printing on fabrics. They also have products specifically for dying and plastics.
“The problem is that all of the products we have come across start with a color and go to clear or to a lighter color when activated with heat (or cold).”

The Mignon Game kit is an Atmel-based game board. It’s got a simple LED display and a few buttons, and is designed for beginners to start writing handheld video games on it in BASCOM’s AVR BASIC.

I first posted about this in 2005 when I heard about it, and haven’t seen a lot on it lately. But this week I met Olaf Val, who makes the kit, and he’s a really nice, smart guy with some interesting ideas and projects. Worth checking out his other work too.
