Mike Rankin created this board with a tiny OLED display controlled by an ESP8266:
MicroUSB powered ESP8266 OLED Board
I created this design as a challenge to make a design under 1″ x 1″ in size.
The hardware is an ESP-01 ESP8266 Wifi module, linear power supply, microUSB connector and a few oled display parts.
The design files and source code are available on GitHub:

Here is a video of the assembly and operation:
miker has shared the board on OSH Park:
my kind of board design! ( small and dense ). Add a small LiPo and a leather strap and it could be your own Smart Watch.
