Got some spare time before holidays and I decided to assemble some simple electronic greeting prototype and this is a result of me finding some free Christmas related icons on internet, I created a thresholded bitmaps of these images 
and converted them to hex arrays using bitmap converter program. In video above you can see 0.96” OLED display hooked up with jumper wires to Attiny85 microcontroller on breadboard, here I am using ssd1306xled library drivers to display images on screen, ssd1306xled is provided provided by - The Tinusaur Project. ssd1306xled library already comes with some test examples which can be easily modified for your needs. Nothing mega epic, but that is just the beginning.
