It's pretty amazing what you can do with these little boards and OLED shields.
Using the Adafruit library and my own 3D rendering code:

By default the Adafruit libs leave the I2C bus at default (slowest) speed. The specs for my OLED weren't listed anywhere, but the highest speed supported by the ESP8266 code worked fine (see video post above for details). This let me easily get 100fps rendering where I was getting 20 or less with the original settings (and it was limiting how much could be done on the CPU even running at 160MHz because it was mostly waiting for the I2C transfers).
