And what looks like an SSD1306 library just for ESPs: https://github.com/somhi/ESP_SSD1306

Maybe just use an ESP8266-01!!! http://www.esp8266.com/viewtopic.php?f=152&t=8776&p=43131&hilit=i2c+oled#p43131

Don't use GPIO9 or GPIO10? http://www.esp8266.com/viewtopic.php?p=38963#p38963

Comment here leads to github based on someone asking my exact question: http://blog.squix.ch/2015/06/esp8266-nodemcu-dev-kit-v10-review.html?showComment=1441111026404#c6491381975651690050 (The library: https://github.com/squix78/esp8266-projects/tree/master/arduino-ide)

Some more libraries to look at if it comes to that: http://www.esp8266.com/viewtopic.php?f=29&t=7841&p=39726&hilit=i2c+oled#p39726

I feel like I need to ask the question: Has any other person actually documented their physical wiring and Arduino code (NOT LUA) connecting a 12E to an OLED using SDA and SCL?! This includes what libraries they used for either ESP-01 and/or ESP-12E.

SUCCESS!

This lib: https://github.com/squix78/esp8266-oled-ssd1306 These instructions (IDE 1.6.5 and example SSD1306Demo with 12E actual pins SCL D4, SDA D2.
