Pixilation has a tendency to also be crude, ungainly, and inelegant by the
nature of the process. It is practically impossible to keep a human subject
completely still or registered in the same position one frame to the next. The
result is a highly active frame that has a bit of a humorous and kinetic appeal. A
pixilated Shakespeare would not be a great match (unless humor or parody is
what you are seeking).
Time-lapse photography, which requires a consistent exposure of frames
over a period of time, has a completely different effect. Events are sped up
dramatically so time feels compressed into a short span. When a time-lapse
camera is pointed at the sky during an oncoming thunderstorm the results
can truly be awesome. Clouds look like waves of ocean water and one can see
the power of nature.

When the time-lapse camera is focused on human subjects or animals, the
effect can be a bit more humorous. The fast and unnatural movements
remind us of early films, when cameras were undercranked and you would
see comedic action, like the incompetent Keystone Kops from Mack Sennett
