Michael Howard is the creator of the Midnight Mars Browser software that permits auto-download and auto-mosaicking of Mars Exploration Rover images.

On sol 1,793, Spirit captured a Navcam panorama containing a view of Home Plate North, the spot where it spent its third Martian winter (and all of the Earth year 2008). Michael Howard has dropped in a computer model of Spirit at the winter parking spot, providing a sense of scale and of the steep angle at which Spirit was tilted in order to catch the wan winter sunlight.
Spirit continued its attempt to bump up the slope of Home Plate on sol 1,715, but its attempt to drive upward resulted in a sideways shimmy instead. An animation of Spirit's motion from sols 1,709 to 1,715 can be downloaded here (Quicktime format, 340 kb).
