Thermochromatic two pixel display

An experiment making a two pixel display using a sheet of liquid crystal thermochromatic ink and nichrome wire.

The pixels are controlled independent from each other and switched consecutively. The total current drawn is approximately 80mA independent on the number of pixels.

The metal ring on the left is there just to keep the autofocus of the camera focused.
