"""Logo demo for PineTime
~~~~~~~~~~~~~~~~~~~~~~~~~

This demo is simply an alternating sweep of the Pine64 and
MicroPython logos. It cycles through a variety of colours
and swaps between the logos every 5 images (so if you change
anything make sure len(colors) is not a multiple of 5).

.. figure:: res/screenshots/DemoApp.png
    :width: 179

The demo also includes code to keep the devie awake making it
suitable to run as an always-on application to demonstrate wasp-os at
conferences and shows.

.. note::

    Due to it's niche purpose and relatively large size this app is not
    included by default in the flash images. It must be separately installed
    and enabled.
