Stuart Young (Australian maker, based in Melbourne) made the base and motor, here's what he said:

FWIW: The drive motor in the box is a Nema 17 stepper motor driven by a Pololu A4988 stepper driver. The stepper driver is controlled by a +Freetronics Eleven (Arduino Uno clone), using the Step/Dir/Enable pins on the driver and a very simple custom sketch to control the rotation speed. The stepper driver is mounted on a protoshield, plugged into the top of the Eleven, so there are no other components. It all runs off a 12V DC plugpack rated at 1.5A. The plugpack is a switch-mode one which works from 100-250VAC, so it should work in any country with the right adaptor on it (essential for +Henry Segerman's display purposes). If required, he can buy a suitable plugpack in the country of display if they won't allow the use of the existing plugpack, as 12VDC plugpacks are fairly common.

The stepper driver was chosen as finding a suitable DC motor that, even with a gearbox, drove the gear at a suitable speed was going to be tricky, and wouldn't allow a huge amount of speed adjustment. Also, many of those motors tend to scream and produce a lot of vibration, which is not suitable for a display.
