    A stepper motor will do 0.1-10 rpm without gears. Though the motion might not be smooth enough. Some controllers support "micro-stepping" which should alleviate that. Haven't tried that though.

    I 've recently controlled stepper (and DC) motors by Arduino + SeeedStudio motor driver: http://www.seeedstudio.com/wiki/Grove_-_I2C_Motor_Driver_V1.2

    @Feha, I could be wrong but I don't think you will get a motor to do 0.1 rpm, I think you will need to gear it, for torquey motors look at those used in Rock Climbing Radio controlled cars.
