kanske skulle vara kul till nåt diy-bygge? en knapp med programmerbar text.
"The RGB24T can be programmed to display any text or graphics on its 36x24 pixel display. The programmable backlight can illuminate the graphic display with many different colors. With a simple microcontroller, you can change the display and backlight once the button is pressed. It's an on-the-fly configurable, multicolor, multidisplay button!"
