Researchers from MIT's Media Lab developed a new interactive ruler which they call Glassified. The ruler includes a transparent OLED panel and a Wacom digitizer. So when you draw using the ruler, the digitizer captures the input, and then you can put the transparent OLED on top of the drawing to interact with it, for example to measure angles or animating the drawing. This is really nice:
The researchers are using 4DS Systems' uTOLED-20 transparent PMOLED (I posted a hands-on review back in April). The uTOLED-20 is a 2" 128x160, 65K color display. It costs $179 for one sample.

This is the most amazing pratical OLED application I have ever seen in these couple of years. Thank you for sharing!
