My good friend Chris McDonald made this extra-great, 2-axis drawing machine for doing time-lapse photography.
Here’s the info from his personal website vanita phone company:
Gertrude uses two stepper motors to move an LED in a very high resolution x/y plane. The movement of the LED is photographed using exposures usually between 30 and 90 seconds. Gertrude can either be programmed to “print” a design automatically (“Christopher & Daniil”, the Hell Yup!: Scanlines shots) or controlled live via a joystick (Open&Close portrait series).
II: Christopher & Daniil not talking (pt. 2 in a series of 2) 
Hell Yup!: Scanlines 3 (Self-Portrait)
Wow, this is super cool! I’m off to go click the link and hopefully see the aparatus!
