Spooky eyes on color OLED by gesture sensor. This "eye" image and basic codes are prepared by original author of SSD13XX library and I quickly modified to work with optical gesture sensor. The Arduino sketch (works for Zero Color2 and ULTIMA) of this sample is uploaded to

https://github.com/kodera2t/ULTIMA_SAMPLE/blob/master/ULTIMA_EYE2.ino

and you can get this board (ULTIMA) at

and gesture sensor can be found, for example,,,,

Have fun!
